Where are we going with this relationship?

I’ve been talking with this girl for several months now. We aren’t officially exclusive per se but we are together. She comes over and spends the night, we hook up, go out together all the time, I’ve met her family, she’s met mine, etc.

The caveat is that we have not had sex. Every time I escalate she pushes away and I respect that and don’t move further. I had my cock in her at one point but she pushed away and I stopped. Couple times she was about to give me head and then she pushed back so I didn’t pursue it further. All we do Is make out, suck on her tits, dry pound, etc.

I have feelings for this girl although I have an abundance of other women in my life and she knows that. I want to be with her as a relationship and don’t view her as just some girl that I just want to sleep with.

She knows I hang out with other girl’s but acts like she doesn’t care always makes jokes like when is Saturday girl coming over and jokes about blonde hairs on my sofa, etc., but I can tell she gets distressed about it although she doesn’t blatantly show it. We were talking about our past sexual endeavors one night after hooking up and I asked her when the last time she had sex was.

She was reluctant but was honest with me and told me it was a few months ago before coronavirus. She was out with her brother and his friends drinking. Her brother said they were gonna go home but she said she wanted to stay out longer and her brothers friend who is engaged would take her back later.

She stayed out while her brother called it a night. Her brothers friend who has a fiancé was going to give her a ride back and they went back to his hotel room where he was staying. She ended up having sex with him that night.

She told me it was a few months ago right before coronavirus but then quickly said it was before we met which was almost 7 months ago. I know it was while we were talking that this happened and I feel betrayed by what it was and how it happened.

Furthermore, the fact that I respected her so much to wait to sleep with her and didn’t escalate further and she slept with this one guy who is engaged and is her brothers friend on a one night stand hurts me like nothing else.

She told me when we first started talking that she doesn’t want to be fooling around anymore now that she’s 29 almost 30 and is looking for someone long term to be with. However, that didn’t stop her from going back to her brothers friends hotel room who’s engaged and get fucked by him.

I’ve been ghosting her for the past week not replying to her texts and went out with another girl tonight which she saw on my insta story. I feel betrayed and disrespected I’ve been with her for months and no sex not even a blowjob and she goes and sleeps with an engaged guy in a hotel room on the first night. Thing is I can’t get her out of my head man what should I do?

How should I proceed with this situation?

Any advice appreciated.
