Ive recently called off my engagement after being together for 7 years. He was abusive to my kids, verbally and physically and was drinking. I had to pay him £180,000 to get him off my mortgage. He paid half that amount in the time we were together but the house prices increased and I didn’t protect my equity in the property. He moved out 3 months ago with just a few bits of stuff in the garage to collect. I messaged him with the list of things. He replied with ‘and the engagement ring ? It’s what you do, return it when you break up.’ It’s beautiful, I love it. It was expensive. AIBU keeping it ? Should I give it back ?
