(regular user, have name changed for this- and am prepared for a flaming!)
Bit of background - DP & I have been together for 2.5 years & have a DD who is 3 months old. I bought my house 10 years ago & as I earn more than DP I pay the mortgage each month & he pays the council tax, utilities etc.
I am about to receive an inheritance that my grandfather left me in his will when he passed away last year. It's enough for me to be able to pay off the mortgage, and there will be some left over for us to get married (we've been engaged for a year) & to save. I thought it would be a good idea for us to put the savings in our DDs name for when she turns 18, to help with uni costs/travelling/buying house etc.
Now comes the issue! My DP has a son from a previous relationship who is 6. He hasn't seen him in 4 years for a lot of reasons, mainly that his ex keeps moving & changing her phone number, so he has no idea where she currently is, but he pays maintenance through the csa each month. When I mentioned my plan to save the money for our DD he said that we should do the same for his son. I don't know if I'm just being mean, but I'm not too happy with the idea of investing money given to me by my grandfather for his son. I think I would see it differently if he saw him regularly, but as there is no contact at all I can't really understand it.
I did suggest that once the mortgage was paid off I would be paying half the household bills so that would enable him to save a few hundred each month for his son if he wanted, but he thinks that he should have a lump sum too, otherwise our DD will have more money when she is 18 than his son will. (I did point out that his ex may well be saving for their son too)
So, AIBU?
