Am I wrong?

So me and my boyfriend got in a fight a few weeks ago and yesterday I was looking in his phone for what his mom said regarding thanksgiving plans and seen that he was talking shit to his mom about me during a fight we had a few weeks ago, this use to happen last year but it was worse anyways I asked him why he was doing that again and he immediately got mad and said I shouldn’t be going through his phone and said that he wouldn’t have to talk shit if I wasn’t such a bitch and that I shouldn’t have gone in his phone. So I told him he needed to go home and he decided to block me in all social media but still text me talking crap saying I hurt him cause I looked at messages even though it wasn’t about that it was simply for thanksgiving. But my thing is why go talk crap about me to your mom tell her I’m such a bitch and you hate me and you spend money on me even though it was a birthday gift when he gave me money. This same person goes and talks crap about me to his mom then comes back to my home and tells me he loves me once he’s not mad and acts like everything is fine. It just upsets me that he does that. I believe that if he’s mad take some time to cool off then come back and talk it out like adults don’t go run to mom and talk shit. Anyways am I wrong?
