I feel like my partner was trying to Emotionally manipulate me and i finally stood up against it. But does that seem like it was actually the case? Or did they have a point?

So. My partner (now ex) sexted someone online 3 days into our relationship.

Before we even started dating. I made my trust issues and anxiety clear. I asked a few times if them cheating was anything I’d ever have to worry about. They said no and promised.

So. They Cheat. I’m very hurt. They ask for a 2nd chance. I gave them one. But because they had already cheated, my trust issues were taking hold. In these screenshots. You’ll see that they mention me asking questions being an issue. But I’m autistic and don’t get social cues sometimes. Should me asking a lot questions have been a problem? I feel like I was justified due to them breaking a promise and hurting me. But were I in the right to do that?

And also. Were they trying to manipulate me towards the end of the screenshots? Was what I responded with justified? I know I did a little name calling. But I was a little emotional and hurt. They also brought up my transphobic and homophobic dad to try and hurt em I assume. Was I in the right to say what I said and then block them after what they said to me? Please help me…
