My girlfriend (25F) believes it's inappropriate for me (23M) to have conversations with female colleagues outside of work.

We've been together for six months now, and it’s definitely been a rocky journey. We both tend to be a bit jealous, and we’ve mostly come to terms with that. In my recent therapy session, my therapist pointed out that it’s unhealthy for two people in a relationship to have differing boundaries. This prompted a conversation with my partner, during which she mentioned that she believes her boundaries are toxic. I agreed, which understandably upset her. I later clarified that I only find one particular boundary concerning: she doesn’t allow me to chat with other women outside of work—whether it’s through messaging or any other platform—even if the topic is purely work-related, like venting about our boss. When I reminded her that she had labeled herself as toxic, she seemed to backtrack. I’ve said before that I’m fine with her communicating with male coworkers, even though it does make me feel a bit jealous at times. She talks to them rarely and usually shares what they discuss. When I pressed her about whether she thinks it’s wrong to speak to colleagues of the opposite sex outside of work, she admitted that she’s a hypocrite and that she doesn’t really want to engage in those conversations. I personally don’t mind that boundary; I don’t feel the need to chat with female colleagues or even male ones. It’s more about the restriction that bothers me, and I expressed that to her. An important detail: before we started dating, I had been messaging a female colleague mostly about work-related issues—like reminding me about missed meetings. Over the course of four months, we exchanged messages six to eight times. When I began dating my girlfriend, I didn’t mention this colleague, not because I was trying to hide anything, but because it didn’t seem significant to me. When she found out about our messages, she was very upset, and we almost broke up. I explained that I wasn’t aware of her boundaries, and we managed to move past it. Now, I’m wondering what you think about this situation. I’m uncertain if it’s normal to communicate with female colleagues in this way.
