So I met an girl. She is 28 and I am 24. We understand us good and everything. In the beginning she were telling me that she had an bf. Somehow we decided to work together and letting other people watching us having sex( in person and on the internet. Don't worry I don't have any tattoos, masks and we barely talk).

One day I was inviting her to the hotel and she accepted, we went up there is where I fell into probably my biggest shittest ever!!! I started to turn her on and she suddenly asked we want we are doing here and why we are here. I responded that I want to have fun. She said that she has already(with her bf) fun. She asked me then what I want from her. I said that I want to have something like f+(I have to mention that I already told her this one time a few weeks ago. I knew also that she has a bf so this was the only acceptable answer[for me, maybe I fucked up already there]). She still gave me a hj and bj. I wanted to confront her the next days about what happened in the hotel but I didn't.

2 weeks later she mentioned that evening in the hotel and said she didn't want to have sex with me because she found it pretty rude that I want to have fun with her without responsibilities and that I don't want to have a relationship with her. I answered" how we can have a relationship when u already have one?" She responded "you see, it is possible "(she was referring to her because she were with me). Before she mentioned the evening in the hotel, we talked about sex fantasies and she said I can fuck her anytime.

From that day(2 months past) we didn't talked anymore about it but it's not more like before. We don't work more so frequently, she doesn't tell me everything. It feels like we are only work colleagues now. And the worst she is lying sometimes or respond to what did u do today :"nothing special "

Should I tell her that I want a relationship? Or ask what her problem is?

Yes I meet also other girls and have sex with. The last was yesterday. For me there is only one possibility to fix it or to destroy it(what would be bad because of the good money, I want to save it and then to open my business)
