I found out he cheated. He broke up and blocked me?

I found out my boyfriend of 1.5 years had cheated on me by sexting another girl and then continuing to keep in contact with her. He matched with her in April on tinder (when we were dating 8 months at that time), and then would send her messages every once in a while telling her how good she looked (tbh, my ex even admitted she wasn’t that good looking. But she was ok. She wasn’t ugly and below my level - so I’m confused why he gave her so much attention and made her look pretty - i guess because he wanted her for sex). Anyways. I found out by logging into his social media accounts. He got mad at me. Telling me i broke every last ounce of trust he had in me. Called me a psycho and blocked me.

The thing is. I’d question him about that girl he cheated with for months (because. I knew he updated his tinder and that was a whole other thing). But, he lied straight to me and something just didn’t feel right.
