I’ve been single for a few years now, but I’m talking with a girl, Lauren, who I was really good friends with a few years ago. We’ve hung out a few times but nothing more than a hug and no serious dates.

I met her years before through my then girlfriend, Sam. I will admit, I cheated on Sam one time when I kissed another girl. It was a mistake and we made up and continued our relationship for more than a year after, but now Lauren found out that I cheated, not knowing really what happened, and is understandably skeptical of my trustworthiness. I have fallen completely in love with Lauren but don’t know how to prove to her that I’ve changed for the better.
