Long story short, I have been with my DP for three, almost four years. We have a DS who is 6 months old. Before we met DP had bought a house with his ex girlfriend a few years previous. Obviously that meant he has paid for the deposit, and the mortgage payments since etc. However when I moved in two years ago we decided to split bills down the middle, that obviously included the mortgage. As far as I was concerned it was both of our house (despite not being named on any paperwork etc).
As our DS is getting bigger we have decided we’d ideally like to move house, but we would consider remortgaging to carry out the work that needs doing for us to continue living here. We were having a conversation about moving the other day and DP said that if we did move, with our new mortgage contract he’d like to go in 60/40. I was fucking livid with this, he said it’s because of the years he’s paid for the house before we met, and the fact he paid for the deposit. I was under the influence us moving house would be a clean slate, and we’d go in 50/50 as we are now a family etc as we'd still split everything down the middle. We had a rather big row about it, and even now I still feel hurt. His reasonings were if we were to ever split he’d get 60 percent and I’d get 40, when that could be 15+years from now and we would have paid the exact same every single month for years. I just don’t see his reasoning. Yes it’s his house, and he has paid more than me over the years, but I can’t help that. I can’t seem to shake the argument, I feel like he doesn’t value me as his equal partner. Opinions please?
