In-Laws😠

Okay, I have to rant because my blood pressure is through the roof and I'm 20 weeks pregnant. My husband's dad is constantly making something up as to why he needs to "borrow" money the evening before my husband's payday. I eventually got tired of it and told him to leave us alone and not ask anymore because he gets money the same as us. Btw, he has always treated me and my husband like shit and is constantly lying in his own favor. However, after calling twice just tonight before my husband went to work to tell his dad and his girlfriend not to message me because we had already said no, his gf does it anyway. I called and told her I was gonna knock her teeth out. (Darn pregnancy hormones) was that a bit much? What else can you do when no matter what you say they don't respect you or listen to the word "no"?! They're driving me crazy. I hate having problems and arguing with people but They make it absolutely impossible to get along with because they don't want anything to do with you unless it benefits them.
