Yeah man cheating is bad, and if your girl were to find out, the outcome wouldn't be good, too much drama

I agree the past should remain the past, I have a similar situation

I've learned that 9 times out of 10, sex just can't be sex, because in my case, feelings got involved and then drama started, so I think you might as well just stay with your new girl, and ride that out

Hope everything works out for you bro
