Backstory is I have a long term friend of many years. She's always been a bit wild. About 5 years ago she split up with her husband when her youngest was just a baby. It was a bad time for her and she suffered mentally for a while. Family and friends rallied to help her. She spent a lot of time going out drinking at that time and we all let her get on with it, even babysitting the kids on a few occasions so she could get it out of her system.
Fast forward five years and this is her lifestyle now. The kids are now 13, 9 and 6. They go to their dads every other weekend but on her contact weekends with them she sends the two youngest to her retired parents and the eldest fends for himself so she can go out and get wasted on booze and occasionally drugs. They also spend a lot of time with the grandparents during the week when she is 'working' (going to the pub after work). I would say the kids spend less than 25% of their time at home with their mum.
The states she gets into aren't good. She will post videos on social media of her and her drinking buddies getting totally wrecked and acting like idiots. I've tried not to judge, it's her choice and her life. But yesterday we were meant to meet with the kids, my dc were excited to see hers and she cancelled last minute. Later on I saw pictures and videos of her smashed in the pub with friends. I felt really let down and asked her about it. Her response is to bring up her past mental health issues by way of explanation of her lifestyle and tell me 'I wouldn't understand with my perfect life' - I've been having therapy myself recently but she doesn't know that and seems to think she's the only one with justifiable problems in life.
Aibu to be totally pissed off with her? I don't agree with the way she's behaving and I hate how she isn't present for her kids. I also hate how selfish she's become and how mental health is something she always pulls out of the bag when challenged about anything because it's not something anyone can argue with. I feel I need to take a step back from her now which I'm sad about as she's been a friend for a long time. Aibu? I have tried to help her but I feel like she is now choosing this lifestyle over her kids and friends.
