Because I am a Christian I have to forgive you no matter what
If that is how you feel, then you have missed the mark by a mile.
Forgive as GOD has forgiven you, the right attitude is GOD wanted to forgive you so very badly that he died for you. Big difference between what you have to do, and what you want to do. GOD does not have to do anything unless He wants to do it because He owes nothing to any one.
If you forgive because you feel you have to forgive then you know nothing about love.
Rom 5:8 But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us
