<human>: Could you distill the essence of the text into 1-3 sentences?

We are friends for only one year and I was in a long term relationship with an other girl (6 years long). We became friends rapidly and we instantly connected on another level than just friendship. We were cuddling often and we would be very close emotionally and physically although never crossing any boundaries. We would often say that we love each other very much and that being together feel so good and that it's so easy to be who we really are with each other. We've also traveled together. This travel has brought us even closer. Sometimes, there was very subtle allusions that we could have sex together, but we were drunk most of the times when things like this were mentioned. She became very curious about other girls but will only talk about it with me. 

Since then, I've broked up with my girlfriend (for other reasons than this particular relationship) and I'm pretty sure I'm not in love with my friend. But, now, she is putting a distance between us saying that she want to be closer to her male friend and she need the kind of relationship that we have but with a guy, that she is missing the affection from a man. Continuing, anyway, to tell me that I'm very important to her and that our relationship is unique and precious for her.

I don't want to lose her as a friend but I also don't want to lose this particular relationship that we have. What should I do? Back off? We've never talk about this ambiguity in the past, should I talk to her now? Also, she's the kind of girl that would often put the fault on others. And, yes, an other thing, she's working with my ex-girlfriend and they have been coworkers/friend for 5 years.
<bot>: Straight friend and ex's coworker and I have a very close relantionship. Seems to wanna take some distance with me and don't know if I should talk to her.
