You are doing the right thing.
I am the other way round to you in that we have my partners children every other weekend.
Today my partner is definitely not in a fit state to look after his children. He downed 12 beers and a whole bottle of sherry last night and sat up drinking until 6:30am.
I’m about to call their mother as the little one is 2 1/2 and is refusing to let me change her nappy and I don’t want to force her and frighten her.
I worry when they are here becasue I don’t want to leave his own children with him so I can go out. Trust me – you’re doing the right thing.
I’m about to ask him to leave my house – he needs to get his life together and realise what he’s got and what he can lose.
Put yourself and your little ones first- good luck x
