I was with my ex partner for 12yrs. When we met I owned a flat. We lived in that flat together for 5yrs. When I wanted to move I tried to buy another property with him but his credit score was low so I ended up having to buy a cheaper property myself. We lived in that new property for 6yrs before breaking up. During those years he paid me ‘half’ the bills. It was never actually half as he never had enough money because he was always getting fines and getting silly APR loans and generally mismanaging money. Asides from that, it was always me paying for holidays, restaurants etc. I paid for our IVF. Now he’s saying that I owe him money for him having contributed towards bills. AIBU by telling him to get lost?
