Wife and I went to some friends house earlier today for a bbq. Our kids came with us (10 & 14). My wife drinks too much, she has a drinking problem. She had a bit too much to drink and at some she started to bug our son who was just on the couch losing his own business playing on his switch, things escalated and my wife’s friend eventually tried to intervene and calm things down. Her and my wife went to talk into the bathroom, I checked on her, she was crying. I then go and talk to my son and figure what happened. Things calm down but at some point my wife made it into our van and decided that she wanted to go home. She was acting like a drunk child and kept telling us she wanted to go home, eventually I start loading up the van and she realizes what I’m doing and starts to get mad at me for packing up the van and that she now wants to stay. The dogs are in the car; the cooler and the kids and we leave; as we’re headed home she’s angry and belligerent and starts to try to find a way to open the rear back door. She yelling at our oldest and I just being mean and saying awful things. I know that if I drive us all home she’ll keep instigating until she falls asleep so I decide to detour to her grandmas to either drop them off or drop her off. I get the kids to go inside and her grandma comes out to talk to her as she goes off on her about how her dad had raped her and how her grandma didn’t believe her (a lot of trauma, never worked thru it) she gets out of the car and we try to get her inside to calm her down and she’s not having it. I can tell this is getting physical (she starts hitting her head on anything and everything) I decide to call non emergency and as I’m on the phone with them she’s trying to leave and her grandma can’t hold her so I try to use my free hand to restrain her and as I’m holding her she goes for my bicep and bites down hard (instant bruising) I let her go and police show up shortly after. The speak to all of us and she gets arrested cause she bit me even if I decided to not press charges they would so that was my Saturday. I feel bad for it coming to this but she’s done this before and separating might be the only option I have.
