His mom..

I can not deal with his mom.. my so and I have another child on the way and a 7 month old. I haven’t told her son anything or kept her grandchild away from her. I try to stay away because she gets like this. She always thinks I’m coming between her and her son. I’m getting really fed up with her bullshit. She’s a grown ass women who can’t afford to pay her bills each month because she’s buys pointless shit. She’s never given me anything but problems and make me not want to deal with her and I personally don’t want my daughter around her. I’ve tried being civil with her, but nothing works..
