Wow yeah it can easily be something as small as that, and we can save ourselves the same and pain of trying to make it work from then on. All my boyfriend liked to do was get drunk and throw everything I told him about my past in my face. The final straw was when we fought and he searched my entire phone right in front of me demanding an explanation for who I was talking to earlier and saying “I know it was your ex” but then when I asked to see his phone, he would not give me the passcode. Probably because after his crazy assumptions he felt justified in doing something bad behind my back. So long! I can finally live my life again. Felt like I was suffocating.
