To be pissed off DP has left me with his ex’s child and gone to work?

My DP has a 15 year old DS with his ex, he was a teenager when he was born as was his ex. They broke up when he was young but they still are good friends and as a result as am I. Some people find that weird but it works and it's better to be civil even though his son is older now.

We have an 8 week old together and his ex has a 4yo and a 16 month old with her ex. She split with their dad when the youngest was a few months old and he has no contact with her or the children. Her 4yo has a heart condition so we help if we can with her youngest when he has appointments so she can focus properly on the 4yo and also due to the hospital being abour an hour and half away by train so it’d be a nightmare with the buggy and it not really being fair on her being cooped up in her buggy

Her 4yo is having his open heart surgery today he's already had a lot of surgeries etc in his short life bless him but his mum is still understandably worried. They have access to the Ronald McDonald (I think it's called?) house but he will be on the HDU/Icu and babies aren't allowed and she doesn't want to leave her 4yo alone who has had major surgery.

We agreed to have her, my stepson is also here obviously. DP has paternity leave of up to 6 months but he has only taken a month so far and is looking for more during the summer so we can go on holiday with our baby and his son.

Anyway, he booked this week as AL as we are having little one for a minimum of a week as the 4yo is likely to be in hospital for at least a week. DP has said he will take things whatever she needs and will be with the 4yo for a few hours so she can have a break but mostly it'll be just his ex as her family are abroad

Except... He's gone into work today because he's “short staffed” so I'm here with a 16mo who just wants to run around and my 8 week old. I know parents have this age gap but this isn't what I agreed to

Aibu to be pissed off?

I mean he has a 16 month old and you have an 8 week old. Either he left his partner when she was pregnant or you have gotten pregnant either accidentally or on purpose extremely early into the relationship.

I don’t often say this but… what did you expect?!

It's not his 16 month old. Read before being bitchy.

The 4 year old in surgery and the 16 month old OP is caring for aren't fathered by OP's DH, the 15 year old is DH's and exs only shared child. The 4 year old and 16 month old are the exs children with another man.

It’s not ridiculous in these circumstances. The 4 year old has been dealt a really shitty hand in life and his poor mother too.

His ‘poor mother’ has kids with two different men and both relationships failed. Terrible circumstances regarding the surgery but those kids have absolutely nothing to do with OP and everything to do with her choosing the wrong man…twice.

Uh huh... I don't know if getting pregnant as a teenager (which takes two), choosing to have the baby and remaining friends with the dad for 16 years is "choosing the wrong man".

Can anyone appreciate that in these times it is not always easy to say No to work . It's special circumstances, a one off . Don't cause an argument over this . I have commented on this subject before - why are so many people unwilling to be on their own with children . It's not supposed to be a competition. OP you are perfectly capable to manage one day .

It IS easy.
You say No, I've booked time off for a reason- that reason still stands.

I would be livid But I'd be livid because he didn't have the courtesy to tell me and just got dressed and was planning on going into work. The fact that they are short staffed is neither here nor there , Tough shit on them It's not up to him to rescue the business, It's up to him to support his wife.
When he comes home, I would state in no uncertain terms that when he's booked annual leave, he takes that annual leave and he does not go into work without having the courtesy to discuss if this is OK with you even if you're not looking after his ex's children. He need to work out what's more important to him making sure his wife is happy or his employer.

This.

Does DH need therapy to work on his assertion?!

Hope you get through the day, @NebulaNomad , a that the surgery goes ok.

You are totally justified in being pissed off!!

Please learn to read. Thanks.

Anybody else still wondering how the 4 year old is?

Yup.

Hoping that the OP isn't now booked to babysit for a funeral and is quietly relieved that she didn't follow the batshit advice and goading to abandon the kid.
