What rights do I have on a property with a joint mortgage when I left two years ago?

My ex and I bought a house in 1997 with an interest only mortgage. We both worked full time and paid into a joint bank account, however, I took a job with live-in accommodation three years ago and the relationship broke down a year later. He expected me to pay half the mortgage which I was not prepared to do but gave him the option of us selling the house.
