The value of an emotion has nothing to do with the intensity of feeling.
Repeat that until you believe it.
First, just some advice, overall it is not healthy to worry about whether or not your emotions are “real” by other people’s standards, although we all do at 16, God knows. Nobody has the slightest idea what “real” love is, and there is no pissing contest to decide who has “really” experienced it. This is the result of too much TV and too many movies that make us wonder “Gee, have I felt what Buffy is feeling right now? (If not, is there a product to fix that?)” Don’t worry about what you might be “missing out on” or whether or not your life is following the same emotional path as “Cosmo” assumes. Whatever you feel, whatever you experience in life is “real”–how could it not be? The idea that there is this one, and only one type of special love that is the same for everybody and it’s like an insider’s club is a ridiculous Hollywood construct designed to sell you products. I am not exaggerating. When you get to the end of your life, you will feel that everything you did was exactly right, because it made you into the person you are, and none of us realy wish we could kill the person we are now so htat some other us could exisit.
Second, No one is doubting the strengh of your emotions–the emotions are the easiest, most instinctive part of a relationship, and they may well never be as strong again asthey are right now. However, insofar as “love” is the stuff that binds two people together, there is so much more to it than feelings–there’s shared memories, there’s sacrificing for each other (real sacrifices, like compromising on a hundred little things, not easy sacrifices, like dying), there’s accepting sacrifices from the other person, there’s the trust you build up only after it’s been tested, there’s learning to work with someone, there’s learning to get over resentment and learning to recognize the other person’s resentment is justified. All these things have very little to do with that heart-thumping, gut-churning, heavenly-choirs singing glorious feeling of rightness you have when you are together–that’s just a small part of love. And I don’t think that you can really understand all the rest until you have mutually depended upon each other for a good while–I’ve lived with my husband for four years and I am learning about love every day.
I saw a lot of relationships in high school, and have watched them since, and there is no relationship between the intensity of feeling in the first year and the long term sucess of that relationship–either in duration or in the overall effect it had on the people involved. Note, I did not say that there was a negitive relationship, but no relationship at all. It is completely random, near as I can tell, and in fact, I think that many of those relationships that did last lasted because people got lucky–they picked a partner for all the wrong reasons (looks, hormones, feeling lonely) and ended up with a great guy/gal by accident. Which is why you can’t point to successful relationships that had rocky starts as examples.
Lastly, I want to say that the duration of a relationship dosen’t really say much about its quality. Don’t feel like the way to prove you know what love is is to stay with this guy forever–sometimes two people come together, teach each other some important things, and then move on. That is an important relationship, with all the emotional “realness” of a 50 year marriage.
