Relationship background: We started dating 2 years back. The first couple of months, she was still “very lightly” in touch with her previous partner (lets call them B). I asked her, maybe it’s better to let the past go if she wants to date me or anyone else. She wanted to stay in touch, and continued until B wanted to stop getting in touch. This was one of the first moments, where I felt not listened. Apart from that, the relationship is good so far. We both respect each other, and care for each other. We show interests in each others problems and hobbies. We indulge in things together. We build things together, so on and so forth.
Girlfriend specific background: She is a creator. She like creating art, but B did not like her art. This demotivated her and she eventually stopped creating art. This is one of couple of other red flags she mentioned to me.
Current situation: We are finally at a place where we have time to go back to our hobbies. She is trying to get back into making arts. I personally like her art, and am more than happy to support her art. One thing she does is puts her emotions into the art making. How she was affected, how she proceeded to stop herself from doing things, how she blames herself. It’s sad and I know about these things. However, she drops features about B into her art. I was unaware, so I asked her out of curiosity, what that feature meant. She tells, it is B’s features. She knows that I am insecure when it comes to her past relationship.
So, I simply pause and we go down an small-ish argument about that matter. I do not want to be her blocker.
What do you think about this situation? How would you want to handle this in a short run and in a long run? Was my reaction okay?
