I have met this girl 8 months ago and we became really close at first I saw her as a friend, she has a boyfriend anyway but he lives in the States and she lives here in Europe. Anyway we hang out a lot like almost every weekend, but as I started to know her better I gradually liked her more and more. She knows quickly what I think, what I like and don’t like without saying anything. I would love to date her but I respect her current relationship even though it is hard and that is why I haven’t said anything about wanting a relation with her. However recently she is taking over my friends who I have introduced to or at least it feels like it and even had a one night stand with one my friends! I feel betrayed and hurt, because I tried to be the nice guy and my friend gets the good part just by meeting her once and getting her in the sack. She doesn’t know that I know, regardless of that she still wants to meet every week with me. I don’t want to be her playmate to entertain her because she is bored or want to kill time.
What are the right actions to take?
