Baby Momma Drama

I took my baby momma, our son, and her sister to Tennessee this week and drove them 7 and a half hours to go see my baby mommas grandparents. While I was there I had to sleep on the floor because I gave my baby momma and her sister the bed which I was fine with. What I was not fine with was how my baby momma constantly argued with me about everything. She complained and said how she does everything and that I do nothing and how she doesn’t need me around. I’ve helped rock our son to sleep, helped change diapers, and bottle fed him daily. I also engaged in conversations with her grandparents and I was really appreciative that they bought us dinner and the nice hospitality. Throughout the week, we were in the car and my baby momma brought up my best friend and family saying how we are all fake and awful people when my family has been very respectful to her they just don’t like the way she talks to me on the phone and in person they think it is very toxic and my baby momma thinks that she does nothing wrong. I got upset and said some things to my baby momma and she said some things back and her cousins and sister all ganged up on me saying don’t call her that and stuff and I just don’t get why she’s allowed to say all these things about me but when I finally say something I’m just the worst person ever. After all of this I asked her to take me back to her grandparents. I needed to get away from the situation and I was frustrated. I apologized to my baby momma and her sister and I went back to the house and stayed there for the rest of the night. I was so stressed out mentally from everything and I told my parents about it all and they said I needed to just come home. So I bought a rental car and drove 7 and a half hours home. Before I had left my baby momma was texted me aggressively while I was at her grandparents house and then the night before I left she apologized but then when I left she got mad again after I had told her why I was leaving. If anyone can give me any advice on the situation or if I should have done something different please let me know. I hate being home and not with my son since they are still in Tennessee but I don’t think I had a choice.
