I have been in a relationship for 10 years, have a 2 year old toddler and live in my fiancées house - owned solely by him. We got engaged when I was pregnant but since then, he will not discuss any wedding plans. It used to upset me but now I don’t really care much anymore if we get married or not. However, I have recently returned to work after maternity leave and am back to earning a decent wage. He has been struggling financially to cover all the bills and his mortgage when I was on ML as I was not contributing towards bills/mortgage. We have recently discussed that because now I am working, I will start contributing to expenses as I had done before falling pregnant. But here is the issue I have- before I was pregnant I would transfer £700 a month to him, which we agreed would be to cover the cost of bills (not mortgage) but that’s way more than all the bills were and really we should have been paying 1/2 each for the bills (excluding the mortgage). I say that because the house is in his name and if anything were to happen to us, I would have zero rights to it as an unmarried partner. I feel like for years I helped him (through my contributions) with some of the mortgage payments and I have nothing to show for it.
We agreed that we would talk about finances soon and I am going to say that, whilst I am happy to contribute £1k-£1.5k a month, I need an agreement in writing that there will be a separate contribution made by me for HALF the utilities and anything over that will be my contribution towards his mortgage, which IF we move or break up will be considered my equity in the house and will be due back to me. Is this reasonable?
