I’m going to go against the majority here.
From what I can tell op was willing to pay her half towards the holiday but when checking budget it’s not going to be possible.
9 months is a decent amount of time dating and to know if the relationship is going somewhere. And I understand ops upset that he didn’t offer to pay under the circumstances.
When dp and I were first together we had a similar setup. Me with dependant dc, working full time, renting, but with little left in the pot after bills etc. dp had no dc, early more than me and had a fair amount of disposable income left after bills.
We discussed a holiday and I was able to pay my half, so we booked a week off work when the dc would be with their dad and looked at options. Discussed places we’d always wanted to visit. Dp then booked and paid for a holiday to somewhere I’d always wanted to visit and surprised me with it. He paid for it all. His reason was because he really wanted to take me to this place, he knew things were a lot tighter financially for me and he had chosen to go into a relationship with me knowing I had dependant dc and a lot more outgoings than him subsequently, and I earned less. So he wanted to take the burden of me paying my half of the holiday off me so I could use it to pay for more needed things for me and dc.
This was 5 months into our relationship.
So I don’t agree that op is just thinking he should pay, but given she can’t afford it I would have expected him to step up a bit, realising this, and offer.
Op, I wouldn’t take his offer though of loaning you the money to pay for it. That just feels a bit like you’d owe him.
Just explain you really can’t afford it this year, but perhaps plan for next year when you can have time to save up for it.
He has entered into a relationship with someone less financially secure as him and he needs to realise and not expect you to be able to match his spend with everything.
If he really wants this holiday with you, then yes I think he should offer to pay, or at least offer to cover most of it.
