Hello, to whom may be reading this any advice is much appreciated and I have an open mind. What I want to know, is if I am over reacting or my boundaries are being disregarded. My girlfriend and I have been dating since February, and she has been honest and upfront with me about everything. Hasn’t given me a whole lot of reasons to not trust her, but still building trust for sure because it’s still fresh. She has a 4 year old child, and going into the relationship she told me that her relationship with her ex wasn’t the best and it was very toxic, but they co parent well and keep things good enough for their young boy. She ensured that when they communicate it’s only business and nothing more, mostly just stuff about the kiddo. I have no issue with them being around each-other for their kid and when dropping him off to one another, my main concern is that she texted me that last night when he came to drop off kiddo she let the father spend the night, assuming because it was late and he lives quite far about 2 hours away. I don’t honestly think there’s anything romantic between them anymore, doesn’t seem that way, but less than a week ago we talked about boundaries and that I wouldn’t be comfortable with him staying the night there. She claims he hasn’t since they were together (they split up early last year, were together for 10 yrs), and she agreed it wouldn’t happen. I feel disrespected, I get it if he was too tired to make the trip back (9-10pm, not that bad?) but she knew I wouldn’t be cool with it and it crosses a boundary because they have history and sleeping under the same roof. Not that anything happened but I feel like it’s principle and respect to keep my feelings in mind. How should I move forward with this? Obviously I’m going to talk to her but just wanted to know what others might think. Thanks.
