My ex cheated. I found out. A few days ago, i texted him some very mean stuff because i was so angry and upset. (Not an excuse. But, it’s what i did it). He replies back with “you are a toxic and hateful piece of garbage. I don’t need you in my life. Good riddance”. Then he blocked me. A few hours later he unblocked me. Then 3 days later he texted me “hello”. I didn’t reply until the next day at 11pm. I wrote “why are you messaging me?” He didn’t reply. What is wrong with him?
