But... my fiancé and I were talking about old lovers.... well first a bit of back story... we have dated on and off for 8 years. He was, no other way to put it, awful to me the first 5 years. Long story short, I walked in on him getting down with someone else and we broke up for about a year. We started to talk again, of my own accord about a year after. He has been great. It's been 2 years and we are engaged now. My problem at the moment is he referenced his ex... and how he'd never cheat on her. Welp, he cheated on me a hundred times... can I be sure he wants to marry me?!
