I picked my children up from their dads this morning. I asked to grab a drink of water to take a tablet quickly before I left and my ex looked shifty and said the kitchens a dump. Went in to find what looked like a party had taken place. I said to his girlfriend blimey did you have a party last night? She said no so I asked is all this just yours and (ex' name) empties? She laughs and said it's been a long week. I counted at least 3 empty wine bottles and around 10 empty cider and beer cans. My ex has always been a heavy drinker and this was one of the reasons we split. But am aibu to be pissed off that they're clearly getting rat arsed while they have the children? I have noticed it and mentioned it before but to see the aftermath this morning is really bothering me.
