My Gf Frequent Outings with Male Colleague Causing an issue

We have been in a relationship for over two years. We both worked at the same company until December 2023, when we each moved to different companies. Our conflicts started when she began interacting more with her male colleagues four guys, two of whom she refers to as “brothers” (though not biologically related), and two others around her age. One day, her colleagues invited her for dinner at their place. She initially told me she wasn’t going, but I asked why she was considering it since there were no other girls involved.

This led to an argument, and she said she didn’t need my permission to go anywhere, claiming I had no control over her actions. Later, she felt bored and, due to some past trauma, wanted to go out for a walk. She called those same male colleagues to join her. I suggested she invite girls from her PG instead, but this sparked another fight. She questioned why she shouldn’t call her male colleagues for a walk, and I responded that there are certain boundaries in relationships.

Constantly spending time with the same group of guys, without any female company, didn’t sit right with me. Despite this, she went out with them again this time to a temple which I didn’t object to, but again, it was just her and those four guys. I asked her to consider how it would look if I started doing the same with female colleagues, calling them out for walks regularly. I don’t engage in such behavior, but I wanted her to see my perspective.

Additionally, I’ve noticed she has a habit of casually holding her male colleagues’ shoulders something I’ve seen other girls do, but rarely guys. She did this in front of me multiple times, and when I raised it, she said there was nothing wrong with it. She often claims all guys are the same. Her previous breakup was due to similar issues talking to male friends on the phone and spending too much time with them. However, I’ve never asked her to stop talking to anyone. I just feel there should be limits.

Once, she asked why I had male colleagues over to my house for a festival when she was the only girl there, even though they are also colleagues of hers. She asked me to invite them and then blamed me. I explained that I was present the whole time, but I questioned why she would go to her male colleagues’ rooms without any female company. Please let me know if it’s right or wrong for a man to address these kinds of issues in a relationship.

I have been spending all my time with her, and when I feel low and ask for her support, she responds by questioning what she should do if I’m feeling down. She says she should not enjoy her time with her colleagues. I don’t call or disturb her during office hours, and I never question her about spending the whole day at the office.
