not necessarily. they're certainly not entitled to it

Resentment is a burden we carry, so yeah I forgive. But if I'm cheated on they join the 'Pandy's dead to me club', I wont think of them, I wont be effected by them and I definitely wouldn't date them again.

Maybe forgiven, as forgiveness is for the victim, not the perpetrator... but never forget.
