Pleasant memories. Can it be erased? It's haunting everyday.

It goes back to 14 years. I was 30 and single then and she was 40 married with kids. We got to know each other online and soon it turned into romantic relationship. We had wild time with s*x on many occasions.

Then i got a girlfriend and ended up marrying her. I was still talking to this woman on and off and once she told that she isn't anymore interested and we stopped talking. But the memories of the past, still haunted me and i made all efforts to forget her but couldn't even when it was zero contact.

Recently i called her up again, to see if there is any change but after a while i felt, it was over for her and she was not interested in the s*x thing.

Any magic wand to forget this. It's been 8 years since she first said it's over but I can't really get over it.
