It is very hard to forget about all of the good memories sometimes. That is normal. I think part of the healing process is to remember that even though you had those moments and shared a love, he did hurt you in a way that should not have happened at all. You were there for him during those tragedies, and you offered your support; he declined and then went to find comfort in another woman? NO. Absolutely not. That is unacceptable. Love is such a funny word isn't it? We can say we love someone, but actions prove otherwise. I think that is what happened here. You feel that he did not show his full love to you. Even though you had good times, did the pain outweigh that good? The way you described the hurt you felt when you found out he was talking to another woman was very profound. I would ask yourself this question: if you did give him another chance, would the relationship be the same? Would you be able to fully trust him now? I know sometimes people cheat or whatnot and they do work the relationship out, but I do not think a relationship can ever be the same after a cheating incident. I wish you the best. I would say do not rush into another relationship, but go out on the date and see how it goes. I wish you the best.
