Your fault

So my bf/baby dad went through my phone, left it in the car. He went through it which I don’t mind he found no texts nothing because I do not engage with nonsense when I’m in a a relationship. He went through my pictures and videos it was a video of me and my ex from last year at this time we didn’t even get back together. Until the summer of this year. So basically he’s mad that I don’t do the stuff I did with my ex to him. First off why would you go through my phone and get mad at something a year ago. I was drunk in the video clearly and why would you want to watch your current gf/mother of your child engage in acts with another man, then tell me he hurt. Idc what type of acts he performed with another woman. Why would you want to know that?
