My most recent ex still hasn't gotten over his first love and its been months since they broke up. It was one of those intense intense relationships - they were totally mismatched and she couldn't accept him for who he was (she only liked him for what she thought he was when they first went out) but by the time she started trying to change him, he was already head over heels for her. He kept breaking up with her and then going back to her, until she had had enough and refused to take him back. And though he insists he hates her and is well over her, it's blatantly obvious he isn't...even the passion with which he hates makes it obvious there are still feelings there.
So when he asked me out months later I of course asked him if it was simply rebound, and he swore it wasn't. But I should have known...he chose me simply because I was the exact opposite of her and he kept telling me that over and over. And after a month of intenseness, after I started to open up and fall for him, after he made me think he felt the same, he broke up with me. Why? He didn't have the feelings for me that he did for her. And he's already, a few weeks later, moved on to another girl.
My point is that, yes, your first love is special. You won't find someone who makes you feel that way again. It's intense and powerful simply because it's your first. But the nature of it is such that it usually never works - too close, too heady and generally, the two people involved are too young. But some people don't move on - they spend the rest of their lives trying to emulate that first relationship and unfortunately my ex is going that way. In some respects, moving on to someone else is good, but it's not if you go into the new relationship expecting it to feel like the first. It won't. You might fall in love again, and it might be wonderful, it might be better than you ever dreamed of, but it's not going to feel quite the same as the first.
I really don't know what to suggest. I can't tell you - I've not been in that situation yet, I was just heading there with the above guy. But you do need to get into the frame of mind where you don't expect your next boyfriend to make you feel like the last one. If you do that, if you head into relationships with no expectations, then there is every chance that you'll find someone who makes you feel better than that first bf.
