How wrong is it?

How wrong is it that I self-serve to the memories of my cheating ex-girlfriend of 8 years ago?

Especially now that I am married with two kids. While she is married to the last guy she cheated on me with and they have 3 children. We've had no contact since her last confession.

They say "move on from your past" to which I say "I live on memory lane."
