My husband has a son from a previous relationship and a son with me.
Its my step sons birthday in a couple of weeks and he has asked for something expensive. It's about £450.
My husband can't afford to get the present DSS has asked for and instead of getting him something else he is saying I should pay half so that he can have it.
I can't really afford this right after Christmas not without dipping into some money I have saved recently for a specific reason.
The savings are for our sons birthday which is 3 weeks after DSS's and I have booked a few things for him and got him a few presents which are costing a bit more than usual but which I'm paying for. Admittedly I've probably gone a bit OTT but wanted to use it as an excuse to get family together as well and as I'm paying for it myself didn't think anything of it.
DH thinks I'm being unreasonable as our son will have more spent on him and if I'm going to spend that much on DS, then DSS should be able to get what he wants for his birthday whereas I think it's unfortunate if DH can't afford it right now but it doesn't mean I should have to take away from what I've specifically saved for DS's birthday.
I do also have savings but I never go into that unless I absolutely have to and I don't think this is a reason to do so. DH could save if he wanted to but he never does.
Yes our finances are separate. We have a joint account for bills but I prefer to keep the rest separate personally as I just find we prioritise different things and this was the most comfortable way for us.
I don't mind contributing some toward DSS's birthday, I always do. But this is usually £30-40 not £200+
