Bf and I taking a break, But i got baby mama drama... help!!?

so me and bf taking a break, cause he live in another state... we talk all the time, but he has 3 children with his ex.. she has been calling me, and texting me harassing me! she lies all the time and claims she is going to get him back.. he does not want her and he has made that clear. she does not get it though.. she claims i cant have what isnt mine.. i acted like a respectable woman that i was brought up to be and told her she needs to grow up and get used to me because whether she like it or not i am not going anywhere. she still tries to get him to have sex with her, and he tells her to leave him alone (not in those words).. but she will not give up! what should i do? we both care for one another, i have a gut feeling in the end we will be back together but she just can drive me crazy sometimes.. other times i just laugh because she just cant handle the fact that he doesnt want her anymore.. ohhh and she is bi and has a wife.. so what does she want him 4? cant have cake & eat it2

Those poor children.....

I'm sure you've heard the expression "when you marry a man, you marry a family". I understand you aren't married, but in this case, she is the mother of his kids and she will likely be in his life until they are grown. Are you willing to deal with this until then? That could be a long time! Maybe, cut your losses and try to move on?

ignore everything she says for a few months.. the more she knows it gets to you then the more she will do it.

Ignore her for a while, if she persists get a restraining order.
