Ok, I'm still new to this posting thing so please bear with me.
I've been with this girl for 3 1/2 months and things have been going great

. I've never thought about the posibility of her not caring for me because we are usually pretty open with each other about our feelings. We have also been in some pretty serious make-out sessions. But our relationship is definately not soley based on physical stuff. We have talked on the phone for 4 hours strsight without even really realizing it.
The Reason that I am writing is because latley I've been wondering if I care more for her than she does for me. I don't really know why though. I guess it's partly because I always seem to have to start anything physical like kissing or even hugs or whatever. And also she sent me an internet survey with the question "have you ever been in love?" and she had the answer "not really". I know she probally didn't mean anything by it, but I know that I'm in love with her. And it just kinda hurt to see that kind of an answer.
And now any thought of saying "I love you" are out of my mind because evidentally she doesn't feel the same way. She's told me that she "really cares" about me, and "I can't imagine being with anybody else" in letters which I usually find comforting, but it still hurts to see that she doesn't want to pop the "L" word. I guess what I'm asking is to please kinda analize my situation, and tell me if I'm freaking out over nothing or If I should be worried. Or the girls could tell me what they think she's trying to say(if anything at all) Thanks guys for your help.
