I struggle too with 'forgive and forget', but it must be so much worse when you were friends with the OW. You describe her as sexy, but she must suffer from low self-esteem to use people to boost her ego. You are the better person in all of this, maybe she was jealous of you and just wanted what you had.
I know it's not good DB, but I wish nothing but the worst for my H and OW. The heartache they have caused is astounding, and yet they hold their heads high and appear to have the perfect life.
You take care Lisa, you're doing great.
