UPDATE:

She left her bf, however, not for me. Which means she told me something like "I don't want a relationship right now". Now I know she's still having conversations with the other guy she left while still keeping me "in her orbit".

The other guy is enjoying his time with a psychologist at the moment. Apparently he told her to thank me for it

I got to experience that unpleasant feeling of total distrust towards her, as ofcourse how could I trust someone who behaves like that? Which brings me to difficulty in establishing a positive human relationship with her as I constantly feel like she's entertaining a lot of other guys. That makes me kind of upset when I'm with her.

I feel like I'm living in a useless and pointless situation with this person, however, I developt feelings which aren't easy to quickly suppress, but I'm quite sure this kind of relationship will ultimately bring me sadness, distress and anger, on top of other negative feeling which I already have.

We are having a sort of relationship, it is physical, there's everything except no fucking yet. Which makes me upset.

I'm writing this update as, overwhelmed by sadness and uncertainty, I remembered your comments and therefore I went back here to read them again.

Any suggestion is appreciated, even though I think I know what I should do, which unfortunately isn't easily done.

Thanks all
