Future mother in law help!?

Girl it is only going to get from Bad, to Worse, to HORRIBLE! Trust me i know my B***h-in-law as i like to call her is the worst ever at first she would make comments towards me and even made me cry one time because of the things she was saying to me how i planned to get pregnant on purpose and s**t like that girl but the last time she made me cry she try to do it again the second time, she put her raggedy old witch finger at me and i snapped (a girl could only take so much) i slapped that b***h finger out of my face and i yelled to her, look! you don't talk to me that way, then she tried to tell me to shut up, i said NO you shut the F up your not my mother to talk to me the way you want to and never get in my face again! And she started crying, but beware they do that in front of the son watch you will see. my husband said shes crying i said good i hope she cries some more that what she gets i held my tongue to long and she never did talk to me with disrespect again.....As of matter of fact she really don't speak to me at all anymore, and i love it that way! So tell your boyfriend to grab his and tell both mom and dad whats up. Oh and you to being young don't have nothing to do with it i was 19 when this happen had a job, car, rent, bills and a baby. So go ahead and open your can of Whoop A** if you have to but only when you cant take it anymore until then kill that broad with kindness! Really hope it doen't have to turn out with drama like mine so good luck!
