Depressed , Exhausted , Panic attacks currently suffering

My Ex broke up with me and blames me for everything and still keeps me on social media and it has been 20days he still hasn't contacted me.

So a week before the break up I caught him chatting with a woman and I asked him about it and he freaks out and stresses out and apologises and after I accepted his apology he starts calling me names like trauma baggage. Just because past history of men cheating on me apparently thats why i doubt him. Since that day he calls me trauma baggage. So on the day of breakup I sent him this video where a man is taking about past traumas and love bombing. He says go see a doctor apparently iam a mental patient he sees no future with me anymore and that swears on our relationship and that he has high standards in my After his message I called him immediately but hanged up. After four hours he calls me back I did not pick up So I replied saying " I respect your decision about the breakup and I hope you find someone according to your standards.

Than he replies saying you always mention breakup. have standards high priority in my life i don't see you i them anymore and told me he will block me after . But what did I do here? Before this break up we broke up in the beginning of this year for more severe reasons but after two weeks he contacted me again . But this time was nothing valid and this is killing me inside.
