Ok I posted a while ago about problems with FIL and MIL so most of you will know we have issues but on the service get on
Anyway:-
My uncle is getting married in July and of course all my side of the family is going. DH has become a good friend of my uncle through football matches and is a groomsman
My uncle did a lot of work for my inlaws last year and knew them slightly before I met DH (but only to say hello to)
When the wedding invites came out we asked inlaws to have DS over night (he is 10 months) and they agreed.
Fast forward and uncle and his girlfriend has invited inlaws to their night do and they have said they are going. So we have lost our babysitters. It was annoying as uncle had said "I feel we should invite them but we know they won't come as they are your babysitters" I thought "you wanna bet?"
Anyway we have asked a few people we trust to babysit and everyone is busy (also all my side are at the wedding)
It has been left that we will leave at 6.30, go and pick up DS and my inlaws will go to the night do. All my family are livid
AIBU to think inlaws should not go as it is my family members and DHs close friend
AIBU to want to slap uncle for inviting them in the first place
PS my mum did have a word with my uncle (her nephew) and said if he invited them we will have no babysitters and had to leave but his response was "if that is the case they won't come and we are only inviting them out of politeness".
Also I know my wider family they will make them feel very unwelcome (even though I have said not too) they will.
