When I was 17 I had a girlfriend that I was head over heels in love with. She wasn't my first girlfriend but my most important. She cheated on me with a mutual friend, just a one time thing and admitted to me what had happened the next day. I was shattered, broke up with her and joined the military.
I never really got completely over her. I didn't hear from her or about her for more than 25 years, I thought of her often throughout the years. I always thought I would have had a happier and more passionate life if I could have found it in my heart to forgive her, but I was young and my pride was injured.
We finally reconnected via a social network site, met for lunch and the feelings were still there for both of us. We were both married to other people by then, but the passion was there and we had an affair that lasted a couple of years. I'm not proud of that, buts what happened.
Sorry to ramble, but to answer your question, I'm still not over her.
I forgive you, let's stay together.
