My boyfriend's mother hates me

My boyfriend and I have been dating for over a year and a half. He is 2 years younger than me but that has never seemed like a big deal. I have also been best friends with his brother (who is my age) since kindergarten. When I first began dating my boyfriend, his mother absolutely adored me… or seemed to anyway. She always acted like I was the daughter she never had. I have been going to their house every day for over a year to see my boyfriend and my best friend.

A few days ago, I went down there after work and it was just me, my boyfriend, my best friend and their older half brother who is 30 years old. Their half-brother, lets call him Chuck, is on drugs and is very disturbed. We came home to find him torturing a dog with a shock collar. We immediately got the collar and receiver and went to check on the poor dog. The dog survived but when I asked Chuck why he did that, he began to assault me. He gave me a concussion and I had to go to the emergency room.

When my boyfriend informed his mother of what happened, she immediately wanted to know what I did to make him do such a thing. He has a history of violence, but she chooses to overlook it. She blames me for her son being in jail and for me pressing charges against him.

Now she is trying to keep my boyfriend and I apart because of it. She won’t say anything to my face but she yells at my boyfriend and he’s getting really tired of it. I really don’t want this event to drive a wedge between my boyfriend and his mother. He doesn’t get along with her and this may put their relationship over the edge. please help!!!
