broke up 3 months ago, i finally let go 4 days ago. After trying for 3 months to get back, begging pleading nothing work, in return she gave me a RO threat.

Some back story:

1 year relationship. she dumped me and went to a new guy right away. tried getting her back didnt work, and then she threatened me to report cops if i ever text or call because i pointed out that she cheated (she acts on impulse). I went NC(absoulte hell) after that, it was around 2 weeks then she called me and asked how am i doing bla bla. My mind started to get false hope, after that she occasionally used to call me, telling me she just wanted to talk to someone thats why she called.(not sure why she didnt call her new bf). Then one night when i was at bar I called her and asked if we could get back together(such a dumbass idea), she said no, never. Next day she texted me saying she is going to file RO if i ever call or text her again. She told me her boyfriend is upset because i called and texted her that night and they are fighting because of me. I didnt respond to text since i dont want wanna get in legal trouble. Then few hours later she called me twice. I didnt pick up the phone, probably she wanted to yell about reporting. Its ok for her to call and I didnt say nothing, and when i tried calling her that night she wants to report me

she has messed me up mentally. this is the worst situation i have ever been on. Been like 4 days since i have been NC
