Such a long story so I will stick to the basics.
Always been very close with my mum but we have also clashed a lot over the years. She's supportive in her way but also likes to have a dig. Like many mums I guess. She's always been fond of a drink but since losing my dad 5 years ago this has spiralled into what I think is functioning alcoholism. Daily drinking, morning drinking, smelling of booze, more recently I've had people contact me telling me they're worried about her because she's been seen acting bizarrely and drunkenly in public. It's got pretty bad.
I struggle a lot with her when she's drunk because her personality changes and she can be spiteful and irritating. I also find it embarrassing if I'm honest.
She has gone from being very involved with my dc to having very little to do with them and my youngest she's never looked after or has much of a relationship with at all. She sees me struggling with work and the dc but doesn't help. I don't think I'm entitled to help by the way, but she is in a position to do so. She'd literally just rather drink at home on her own. Despite this I still visit often and try to include her in family holidays, days out and so on because I love her and I don't want her to be alone. But as soon as we get anywhere (day out to the beach last week for example) she is immediately on the lookout for the nearest place she can get a drink. Never really focused on the dc.
I guess resentment has been building for a long time and today it all blew up as she undermined me in front of my dc and then we got into a row. I said some things I'm not proud of in relation to her drinking (she had been drinking at the time) and now I feel shit. We rarely fall out because her drinking is like the elephant in the room. I've said my bit about it before and nothing ever changes so she knows how I feel but does it anyway. She doesn't want help. She doesn't want to stop. This is her life now.
I just feel so conflicted. I so let down and sad that she doesn't help or want to spend time with her grandkids. Im angry but I also feel terribly guilty for losing my rag and being nasty. I don't know where to go from here. If there are ever any difficult talks or disagreements we tend to just not talk for a day or two then move on like it never happened but this one feels a lot more serious. Any advice would be appreciated.
