Old confessions

I was romantically involved with this girl I'll call Carol between 1990-1993. I loved her the best I could and with all my heart at the time we were together but I wasn't always honest with her. I never cheated on her but spent alot of time with a girl I'll call Loose Lucy and never told her about it. In fact I kinda lied a few times about what I had been up to. Not planning on or wanting to see her again necessarily but if we ever became friends again could I gain her trust again. I'm not really looking for advice I just wanted to share.
