Inspired a little by a thread yesterday.
Just to get the background - DP has 2 DCs with his ExW. He pays over the CMS recommended amount to ExW (20% of his pay) and we have the DSCs 2-3 nights a week. DSCs are both at primary school. When DP and ExW were together, they rented a house. ExW still rents. I wasn't the OW. All the adults get on, but only for the sake of the children.
DP and I have been together 3 years. We bought a house together recently as my house was not big enough for us all. When we met I had a 2 bed. I sold this and we bought our new home. DP didn't have any savings, (he was and still is paying off joint debt from when they were married), but his parents gave him a generous deposit. It wasn't as much as mine so I own and pay 60% of the mortgage and DP 40%. This works for us as DP pays maintenance and I earn more and my money is protected if we split etc.
Bills etc are split 50/50, including everything for the DC/DSC. DP and the DSC come as a package so I'm happy paying for them. I love them all.
ExW has been making comments about 'your big house' to DP and has asked him to up his maintenance by 25%. DP cannot afford to do this. If he pays more money, he would have to cut what he pays towards the mortgage/bills and I would have to make up the difference. Which I could just afford but it would be a stretch.
(FWIW it isnt a 'big house', it is a extended 4 bed semi on an estate)
DP talked to ExW and suggested that she works more hours if she needs more money. She currently works about 16 hours a week. DP said he would have DCs more to enable this. We both have flexible jobs so we can do school drop offs/pick ups.
ExW said she doesn't want to work more as she wants to be there for the DC while they are still young, DP pointed out that that was her choice but that he shouldn't have to pay more because she didn't want to work more. DP would love to work part time to spend more time with his DC but this is just not financially viable.
The DC have private music lessons (just started and initiated by ExW not DCs) and private swimming lessons (£20 a week each!) which DP suggested that they change to group lessons if ExW cannot afford it but ExW does not want to do this.
I understand it must be difficult for his ExW to see that DP has a bigger house but this is due to us having 2 full time wages coming into the home, his parents being generous and the money from my old house.
Is DP being unreasonable to not want to pay more?
He feels he pays a fair amount and also buys clothes, contributes to uniform/shoes etc for the DC. I know this should be between DP and his ExW but it would effect me if he paid more.
Just for context, DP has a battered old car and rarely buys himself anything as he can't afford it. My car is slightly newer but by no means flash.
