Its quite a long story so I will try and do a short version.
My MIL has always been a drinker and I've always said she was a high functioning alcoholic. She will deny this though. She drinks every single day. At lunchtime in the pub and then two or three bottles of wine a night. Shes only ever had supervised access with my son who is 18 months old purely because my own mother in ad an alcoholic and I was badly neglected and abused as a child because of this. Anyways, about three months ago my MIL took a funny turn, confused, vomiting, delirious, just saying off things and living in a dream world. I took her to A ,& E and she was admitted, all sorts of tests. She has lesions on her brain basically alcohol related brain damage. They said she had to stop drinking. She was detoxed in the hospital for a month. Came out and of course started drinking again. Since then she has steadily got worse. Delirious behavior, confusion, living in a.dresm world, she's become aggressive and hostile. My father in law has been staying with us because he's been trying to limit her drinking and she gets aggressive and threatened to.stab him and is physically abusive towards him. He is 75, she is 58. She's been coming to my house, banging, kicking, shouting, she even assaulted me. She told the police that my partner beat her up and then told anyone who would listen the same. She's spent stupid amounts of money on household items that she doesn't need, she even paid for a wedding for me and partner, ordered dresses,.suits, tiaras. This was all in her own head. Paid for holidays, hot tubs, all sorts of random shit. She's been arrested in town loads of times.for causing a nuisance. We just cannot reason with her. I called social services and crisis team. She was assessed and sectioned under a section 2 but only kept for a week because they say it's purely alcohol related. She will not stop drinking. The most of stupid ridiculous things she has done just goes on but I'll be here all night if I was to share all of that. Anyway. AIBU to ban her from my house. I've banned her from my son and while she's having a few days of sanity, she will not accept responsibility or apologize for everything she's put us through so I've said I am done with her. I don't wish to see her or speak to her, she will not see my son ever again. Just to add one of the many times I've called the police to have her removed from my property the police put in a safeguarding about my son against her and I've had social on the phone asking me questions about her and I've told them she will not linger be anywhere near him. My partner thinks I'm being dramatic because she's "ill". She is choosing to drink. She openly admits that it's her ,"lifestyle" and she won't stop for no one. She reminds me of my own mother. I've not spoke to her for almost 10 years because of trauma she caused me growing up so I've no issue cutting off my MIL. Would other mums feel the same in my situation,,?
