Background info is I'm pretty needy right now, and have been for a while, on the 'girls find me attractive' area. 1 hour prior to the dreadful sentence I heard this cute teen saying she wouldn't mind her mom dating me cause I was cute, which was the best compliment I got all year. But then...

I told my ex-gf, who is going to have sex with me sometime next week, that she was still my passion. She looked at me, shaked her head and said 'No. Stop it.", implying that she didn't think of me like that. Also, I tried kissing her and she said "no. We are not girlfriend-boyfriend." "You mean we won't kiss when we're having sex?" "No, that's different, we can kiss then".

Anyway that just drained me, because I thought that wanting to have sex with me implied that she felt attraction which implied she would like kissing. Also, fuck I do (or did because the sentence was like a sucker punch) feel passion for her and I don't want to feel bad for it. I don't want her back as a GF, but I do have feelings for her and want to fuck the shit out of her. Thought she might feel a bit of the same.

So what I really want, or hope, is that you guys convince me that it's ok for me to feel passion for her and that I shouldn't feel bad just because she thinks I shouldn't feel/say it. Am I right? Can you help me making sense of this?

EDIT: Maybe relevant, sex will be in the context of a threesome.
