Most Helpful Guy
"I could be totally into a guy, but he never seems to believe that I am."
My suspicion is that this holds the key.
"Tried to make sure he new I was there for him and I needed him."
From this, it appears as though you know that guys need to feel like they are needed by their partner. But even though you might be aware of it, I suspect this is where you're falling down.
Maybe it's the way you put that *you* would be there for *him* before that you needed him. I'm not sure. It certainly gives off the vibe that as a strong independent woman you're not really as in need of him as he might like.
And a guy doesn't have to be majorly insecure, to feel that if a woman is too independent, to the point where she can get along just fine without him, then she can't really be into him that much.
I would say that, in future, try to show a little more reliance on the guy. And don't be so quick to put yourself forward as his support mechanism. Try giving him the impression that he can be independent, and solve problems for himself, but that you need him as your support mechanism. (Even if you don't.)2THIS IS NOT RELEVANT ANYMORE
