Little run down first off. AND I know this sounds exactly like that movie 500 days of summer.... I met this girl and became great friends with her a little over a year ago. In this year we have both grown very fond of each other and consider ourselves best friends. It was one of those situations where we met each other and just hit it off and started hanging out alot. We hooked up with each other for a few weeks early on, like in the first few weeks I knew her, took her out to dinner a few times and ended up having sex with her. Mutually without saying anything we kind of just stopped for a bit of time, but after a few more weeks we would eventually get drunk and make out, end up starting up sex again. Sex isnt like a frequent daily / weekly thing between the two of us, but sleeping together is. . . This process has continued on back and forth for the past year. Weird thing is we have never talked about it, never mentioned it, its just something that happens. So fast forward to the new year, we are still hanging out, probably more frequentyy and I began to develop romantic feelings for her. I could feel that she was beginning to open up to me a little bit more, revealing intimate details of her life and past relationships. I was recriprocating as well. Friends meet us and think we are dating, and usually ask how long we have been dating for etc, in which we respond we are just really great friends, but everyone knows we are pretty much with each other i guess. Not being one to want to screw a good thing up, i continued on for as long as i could just playing her game of hot and cold. sometimes she is fully in to me and sometimes she is not. Finally last night I asked her "What are we doing? is this going anywhere? Should this go anywhere or should we stop before we end up destrorying our friendship." I explained to her that I would be happy either way, we just needed to actually define what we were getting in to. She responded by saying, She has been thinking about it as well lately, and she is sorry that she is so indecisive but isnt sure what she wants. . . she has to think about it, since we are best friends and doesnt want to ruin that. What do I do? keep waiting and going back and forth with her? RUN? continue to be her friend and pretend nothing happened and that we never brought it up? Do I give her an ultimatum nad say look I really want to be with you I just need to make sure you want the same as well? HELP this is driving me crazy.
