My (25M) gf (21F) of 7 months use to date girls, she lied and said she never kissed one in the beginning of the relationship but then I come across old pictures of her kissing girls and posing in the mirror with the same girl she’s communicating with til this day.

So my girlfriend started a new job, she comes to me saying “this girl is always staring at me in training, she’s weird” and then the next day her and the girl were talking. The next day she’s riding with the girl to McDonald’s. So said “you just met this girl you don’t even know her, but yet you’re getting in her car” ofc she comes up with all kinds of excuses.

My gf birthday is Friday, I’ve told her that I’m planning stuff for us, for the whole weekend. Then days later she comes to me saying the girl wants to do something with her for her birthday. First it went from going out to eat and then it changed to going to the club. I asked when, my gf said Friday night. “So fuck what I planned for us right?” And she said she was just considering it. How are you even considering going out with this stranger when I’m literally making plans for us?

Then today they went to breakfast together, the girl picks her up and drops her off to and from work all the time. Since my gf has started this job 2 weeks ago I haven’t seen her. But I really feel weird about her being all secretive about this girl. I don’t know a name or anything. So I told her if she goes to the club with this girl I would break up with her.

I don’t see how you’re so open to just meeting up with a stranger that you don’t even know. She say the girl has a boyfriend but then tells me the guys that sit around them at the table at work is only there because of the girl. So how am I supposed to trust her to go out with this girl? My girlfriend swears she doesn’t like girls anymore but I feel like that’s a lie. I’m just over this whole situation. We’ve already had past issues with her losing my trust and lying to me. I broke up with her and she said she would do anything to help me ease my mind. But now all she has is excuses.

I’m thinking about just breaking up with her. Would I be wrong?

TL;DR my girlfriend is hanging out and going out with a new female from work. Already talking about going to the club and they’ve just met. The girl is not trust worthy and I know my girlfriend is bi. Thinking about just breaking up with my gf.
