My family live abroad (we are in UK) and a close relative is getting married. Me and DH have been invited obviously and although it's a childfree wedding, a few family children are attending as they are in the wedding party (bridesmaids etc..) our DC (3yo) being one of them.
Because of the distance to travel we are staying with family for a week with the wedding happening in the middle.
We are not well off at the moment and haven't been able to afford an abroad holiday for a number of years, my mum and dad are covering a lot of families flights over there and we are staying at their house. I cannot wait as like I say we haven't had a holiday in ages and DC will have a fab time too (there is a pool and stuff there).
My husband's ex has hit the roof basically. She asked us to cover part of this week with DSC but obviously husband has had to say we can't as we are away and why. She is pissed off that we are 'going on holiday' without them when we have never taken them abroad (never been able to afford school holiday prices!) and she thinks it's terrible that we are going with our child and not them.
Tbf she does take them away most years and we never have other than the UK which we do every year but we can't afford it. She also goes away plenty on her own with her partner too but she says that's different because we are taking our child on this one (yes because they are part of the wedding!).
Husband is a bit of a worrier when it comes to his ex as she has on occasion refused to let him see them when she's annoyed at him (although this has never lasted more than a week or two).
Am I being unreasonable in thinking this is fine, it's a family event, we aren't paying for it and it won't be every year.
