AIBU not wanting to take stepchild on last minute holiday?

[froglet15327]

Have just decided last minute I want to go on holiday for child’s 1st birthday just to a caravan park due to money being on the low side (I could do with the break more than anyone). I feel awful but I don’t want ss to come which I know last minute mil is going to suggest we do. SS is 9 and at the best of times very difficult to deal with, throws a tantrum when they don’t get what they want, demands absolutely everything, swears( which makes me so uncomfortable) and sometimes back chats or just becomes very rude towards me when I’ve asked him something. I really want just a calm easy holiday and I know it won’t be that if he comes. He’s going on holiday abroad for his birthday next month with his mother so it’s not like he never goes on holiday and he went with his dad twice last year whilst I was pregnant.

His father has never had his own home for his child.
He's just a user loser moving from girlfriend to mother, to girlfriend to wife.
Having children but not providing for them.
He's a total waster.
What a pity you had to marry him.
Get him out of your home.
Send him back to his mother and co parent.

I go away with and without the SC all the time. So go.

I went away without my dsd multiple times including luxury holidays to Asia and the US. It is your holiday, don’t let anyone tell you who you need to be including in it. Women need to stop apologising for everything , seeking permission and approval and trying to keep everyone happy.
Selfishly prioritise yourself and your dc and don’t apologise for it.
best thing I’ve ever done when I applied the same principle to my blended family life. I don’t like spending holidays with them-they aren’t coming- simple. My husband can decide if he’s coming or not, he always chooses to come.
