Baby mother drama

My bf and I have been together almost 4 months but we've been friends for about 9 years. He has 2 boys ages 10 & 12. We get along fine....its the mother that's the problem. She doesn't like me because I'm dating her son's father. Ok so here comes the fb drama drama at his house over the phone u name it she's doing it. So he cuts her off...well now he throws up the fact that he cut her off every time we get into any type of argument. I think he still has feelings! We are taking some time apart but idk if I want to deal anymore. Wut should I do???
