my gf broke up with me after one year of relationship. five months ago then she started dating another guy after their first date she text me.

that i brake your trust and stuff punish me. i did say lot to her that day after word she promise me that she will not talk to that guy and if she talk with him i can do whatever i want with her . then after month we stop talking. because she started liking another guy we both agree with that. but after some time i found out that she started dating same guy that she promise me she will not date him. so i text her and told her stop doing that. now she is telling me if i try to text her she will call cops. but i never try to follow or try to approach her. now i m depress that she played with my feelings. i told her if you keep dating that guy i will tell your mom about all this. we have some common friends she told me that if i even mention about her anything dating me and another guy she will call the cops on me. if i share this with someone. i just wanna talk to people that she did that to me. i just want her to realize that she played with my emotion. if i tell her mom,is this crime
