DP is childless, however I have two pre-teen kids from a previous marriage. We've been together for three years and have our own places but are unlikely to move in together till the kids are a lot older. Neither of us has any desire to "blend" the family and/or announce DP is a step-parent, as the current situation works very well as it is - DP stays over quite often, including when I have the kids and they get on together brilliantly. We also go out as a group, do activities together, etc.
After DP first got to know the kids, last year, he raised the idea of getting them Christmas presents (as we aren't really blended and "mum and step-dad", so he doesn't contribute to their main presents from me). He wasn't sure what to get them, and we ran out of time, so in the end he gave them some money to spend. When DC1's birthday came around he suggested we go to a bookshop and he'd buy him what he wanted there, which we did. When DC2's birthday came around he didn't even bring it up. I ended up buying a book for DC2 myself, wrapped it and said it was from DP (who wasn't there, which was fair enough as he had work commitments) thinking I would ask him to pay me back later.
We're now in the run-up for Christmas and DP has just gently ribbed me about how I'm still buying presents, when he's apparently finished his list. The thing is, I know he's not got anything for the kids. Given we've set a precedent, I feel they're going to be let down when the day comes - they're going to ask where DP's present is. DP will be spending Christmas Day with his family so won't be there to experience this. So I feel it's a bit crappy - yes, he's not their Step-Dad but he is in their lives a lot now. I feel it sends a message he doesn't really give a toss about them.
In fairness to DP, he's had a lot on with work and his family, and he is a bit on the spectrum so most likely just completely didn't think about it. However, I know for a fact his parents - who the kids have only met two or three times - will have got them something, if only a box of chocolate bars each.
What do you think? AIBU to think I should prompt him to get presents for the kids, even if only a small and token thing?
