Looking for some thoughts on the details below. Ex lives in family home with kids (3) and we are separated over 3 years. We each pay £800 to a joint account to cover joint mortgage and house bills etc. We've began discussing what will happen to the house, ex wants to take over the mortgage but to do this will be reliant on a £700 payment continuing as the CM payment. I take kids EOW and 1 evening a week. I'd prefer they don't have to move but I'm uncomfortable with their living arrangement being reliant on child payment. Am I being unreasonable to think my ex should be able to allow their housing independently, and my CM payment should be an addition? Happy to hear experiences!
