Stupid

So I'm done with my boyfriends mom she took away what I gave my son for dinner and gave him something else and I told my boyfriend then she proceeds to call me a tattletale and say I'm a bad mom and threatened to beat my a** I've tried to get along with her but all she does is start sh*t and try to tell me how to raise my child she's 50 and acts like a child goes and tells people that I threatened her and told her to leave which I told her to get out of the room causes was making my son cry just tells lies so she looks like the victim I've never done anything to her
