I am currently in a situation were me and my ex Bria (Using fake name for story) have been talking a lot for the past months. We dated 3 years ago and have been friends. We talk pretty much everyday, even goes to sleep on the phone. We have had talks of rekindling our relationship but there is a stalemate. When we broke up in 2019, i did move on 5 months later and met a new woman. We ended up dating and the situation looks as if i cheated on Bria. I have said numerous of times that i did not and have admitted to moving on fast. She wants me to apologize and i have a hard time of apologizing for this situation. Not because I'm prideful, but my character and integrity is in play. I would be apologizing for cheating and i absolutely didn't. What should i do?
