Infatuation or love?

She is married and also a friend of my mother's.I always kind of got the feeling that she maybe was into woman.I came straight out and told her that i was attracted to her.I also asked her, if I was the only one that felt that there was like a sexual tension between us? And she replied" that no it wasn't just me".I found myself often telling her more and more of how i felt. Then one day I got the courage to ask her if I could kiss her.But she always made sure that she reminded me that we could just be friends and that I couldn't kiss her.That it would be so nice if circumstances were different.We kissed and more than once. When we did kiss it was so much there.It was just kissing and open conversations. Also lots of smiles, long deep eye contacts; basically eveything that signals attraction. Then just yesterday I told her just how deep i was into her.She possess my every thought.Try to find excuses to call her.I wake up in the middle of the night and she is on my mind. I am constantly wanting to kiss her when am around her, but I so feel that vibe from her too.We are always making eye contact from where ever we are in the room. Try so hard to not let others see, but they notice the giggles, the looks between me and her. Constant flirting. I am so sad and hurt when I cant hear from her or when I can't see her.I told her that I thought it was infatuation.Now she finally admitted to wanting me as much as I want her. She saids that in the beggining she was all for it, but then after the kissing went down her conscience started to eat at her.Now she knows exactly how I feel for her.I could see myself serious with her and that is strange. I just want things and her to go back to the way they were. Things were going to get good. Either we would of fallen head over heels for each other or we would have had sex by now.Some things she says sound sexy and seductive to me.Im confused because her knowing all this; still allows me to flirt with her. She spends an amount of time with me on the phone, but then there are other days were she hasn't called me once and won't.When im down, bored, or to deep in my own mind she distracts me. She is like a drug to me. I am addicted to her. When am around her or with her nothing else matters.I am in to deep now. I can never go back to being just her friend and I want too. But so much more exist there. I think it's best sometimes if we never speak again but I can't find myself to do that. I can't imagine never talking to her again. Im afraid it's turning into love. I know i can't have her all to myself, but I want us to still hang out and kiss. I want to mess around. I want it to be a mutual thing between us.I want to be her intimate friend.I want to be able to kiss her with out fear of what's gunna happen if I do.Im I normal? Is she into me too?I sometimes want to tell her I love you when we hang up.Is it coming from both parties? What do I do? WE are both woman.
