If you asked me, I don't think I can. I'm still doubtful that I will even forgive him. I met him on daily basis now, and all people in my family already asked me to forgive him already. They want me to accept him back because they can't deal with another issue in this family. Basically they want me to suck it up.
I have no say in this matter so I never said I would forgive him, and I only said I need time. Basically, I can't see this man already change. He still the same, self centered man posing as a selfless human being. His apologize is a justification for what he's done, and I think what he need to repeat again in the future. So yeah, I would never forgive him.
If you are not under pressure to forgive him, I don't think you should. Take your time. Until you feel you are ready and also WANT to forgive him so you can say goodbye to that part of your life. Well even if you are under pressure, you don't need to forgive him. It is all up to you.
