Been with DH 5 years, married 2. He split from ex 7 years ago. No kids.
3 Stepkids aged 9, 9, 11. M, F, M. They stay EOW + odd extra w/e. Some of every holiday unless they have plans with extended family on both sides in other parts of UK. Good relationship all round.
Our household income 45K. London. Both work full time but he earns 60%. Currently own 2 bed flat - kids have bunks + double which they rotate when they stay. Maintenance is £365pm.
Ex wife is a nurse working PT because of wrap around childcare issues. Claims CM is too low for her to work FT as local hospital has no vacancies for office hours roles that she could get due to speciality. This has been ongoing issue because she wants more money/clothes/uniforms from my husband when it should be covered by what he gives. Husband took advice from friends to call her bluff and suggest he take kids more/become RP which I didn't think she would agree but she almost bit his hand off. Her friend is going to teach in Dubai and wants someone to house sit from when she leaves in April which would let her pay a smaller amount of rent so she could save to buy her own place as she has been renting since the split at market rate. I know all this because it is what they discussed with a mediator and he literally came back with notes to explain her points and suggestions for how it could work. Kids are okay with it too.
Situation now is that we are going to have to get a bigger place which will mean more money. Plus pay for food etc extra Bill's and she only gives £250pm maintenance for it all. Commute and everything will be on us. She will have them 2 nights a week minimum according to her schedule as she is going to do a Masters and stay part-time. She wants to do this because she said it will boost her career prospects and make up for the time she has been RP.
I want my husband to reconsider agreeing to be RP and use the money we would be spending to boost what what we give to maybe 600+ a month. I've worked out that it is going to nearly double our monthly expenses once you factor everything in like bigger mortgage, commutes, dinner money, uniform, clothes, football boots, martial arts equipment, leisure money, school trips extra utilities and Bill's, pocket money, presents. Unless we play the bad guys and make some serious cuts in long standing hobbies and commitments. My 11 year old stepson plays football at a high level which isn't cheap but something has done for five years and his mum has kept up all this time. The 9 year olds do martial arts which also costs money and time. When we sat down to crunch numbers and I put all these things down with the help of my sister who is a single mum so helped me break it down, husband says I'm being pessimistic and with child benefit it will balance out as he doesn't have to pay and she will pay two thirds of what he was paying but the numbers don't lie.
How can I make him see what we are getting into?
