Generally speaking ( I put the generally in bold because I don't want there to be any confusion that I am making a general statement that is not intended to upset or offend anyone ) I think that Stelena and Delena fans have different views and opinions about what love is or what it means - in real life and in the TVD universe.
And you know what? That's fine and it's normal because in the real world, love does mean different things to different people. Different people look for different things out of a romantic relationship. Some people want love to make them feel safe and secure, they want it be something that they draw comfort from and that keeps them grounded. For them, love or a love relationship is like an anchor that keeps them steady while life rages around like a hurricane.
Now personally, I think that whatever kind of love you're looking at - and here I'd even include other types of love, platonic, familial etc - it's going to have those elements of safety and security. Knowing that you're loved is always, I feel, going to be reassuring and provide comfort.
The difference is in how close to the top those things are as your priority. Because there are other people who see love as being something that can turn you upside down and inside out; something that can throw your entire life and emotional balance into complete and utter chaos but at the same time make you feel so happy and so alive that it's worth it.
And in that kind of relationship, things are admittedly going to be volatile sometimes; there is perhaps less security than in other kinds of romantic relationships. The bad times or the lows can be very brutal because you're always hurt the most by the people you love the most. And vice versa as well. For some people the risk of having the relationship implode in spectacular fashion is worth the highs that you can reach and for other people it isn't.
For me personally? I fall into the latter category. I'd rather not be in a relationship than be in a relationship where I'm never miserable but I'm never ecstatically happy either. But what can I say? I'm a girl of extremes
I'd rather love intensely and take the risk that it all falls apart in spectacular fashion than sacrifice spectacular moments in favor of knowing that it won't fall apart.
So when it comes to the TVD ships, my personal opinion is this. Right now, Stelena is a relationship that is safe. It gives Elena security and comfort; it helped her make sense of the world after her parents died. As a general rule (unless he goes off the deep end or there are extenuating circumstances or something) I don't think she'll ever be unhappy with Stefan. But will she be crazy, giddy, over the top happy?
They've had moments like that already and will probably keep having them. But in the long run? I feel those moments will get fewer and farther between unless Stefan makes some changes/progress in dealing with his issues. The fundamental thing for him is this; until he can accept that he deserves love and deserves to be happy, he will not be able to make her happy.
And how is that different for Damon I can hear people asking; he doesn't believe he deserves love or to be happy either.
Well, I'd answer this. There are a couple of distinctions that need to be made between the brothers on this level. One is that, Damon might believe that he doesn't deserve love (mostly because he's never had it) but he craves it. Stefan has love, has always had love, and is choosing now to reject it for his own reasons. Secondly, Stefan knows he can be happy and is again making a choice(not necessarily a conscious one) not to allow himself to have that resulting from certain insecurities. Damon, on the other hand, doesn't think he can be happy; he doesn't think he's allowed which is a little bit different from thinking that he doesn't deserve it.
The result of those differences imo is this and we're back to the because/in spite of thing. As I said, Stefan has to accept/realize that he deserves happiness in order to make Elena happy in turn. This is because as usual, Stefan's love is conditional; it depends on things to exist and in this case it depends on him resolving his issues.
Damon on the other hand is Mr. Unconditional and he - contrary to his brother - wouldn't, at least in my opinion, allow his own issues to overshadow his feelings. I'm not sure I'm really explaining this well but essentially what I mean is this. Damon, in a relationship with Elena, is capable of doing whatever it takes to make her happy, however extreme. His energy is all focused on her with little thought as to what it will cost him or make him feel.
Because Damon has it in his mind that he can't be happy, I don't think it would occur to him that making her happy, might result in him being happy himself. If it happened, I think it would be a surprising side effect to him. Whereas Stefan knows that he can attain happiness but isn't letting himself go there.
And on a more general note as I've said before in other posts, there will be more risk involved for Elena in loving Damon because he's not safe. There isn't a lot of middle ground with Damon and as a result if Elena starts caring for him, she has to go all the way with it because the only alternative is to basically hate him and I don't think she's capable of that anymore.
A Delena relationship would be more volatile, I don't think there's any question of that and it's because they bring out a complete range of emotions in each other. They make each other angry sometimes, annoyed other times, smile sometimes, vulnerable sometimes. Eventually, they'll make each other happy sometimes, hurt other times. It won't be easy or safe between them, but imo that range of feeling - being able to feel all of those things and being with someone who brings that out in you - is how you know that you're really living your life.
There's no reward if you don't risk. And Damon will always encourage Elena to take risks. Whether that's because in and of itself loving him is a risk or whether it's active in that he's encouraging to explore the world and try new thing or just giving her the space to make her own choices and mistakes.
That in particular is something that I think will set Delena apart from Stelena; both brothers are capable of being her protectors and safety nets. But they approach it differently.
Stefan will be there to catch her immediately if she begins to fall because he wants to protect her from absolutely everything.
Damon, I think has slightly different instincts so while of course there will be times when he'd be there to catch her if she started falling, I think there will also be other instances where he'll recognize that she needs to fall; needs to learn from a mistake or see the consequences of a choice but when that happens, when she falls, he will always be there to pick her up again.
Right, I have rambled on more than enough so I am shutting up now.
