Same struggle

My husband was having a long distance affaire and eventually left me after many lies and hurtful actions. Then Three months after leaving me he started another relationship with a young local girl. I want to forgive him for my own peace of mind but like you I must face this selfish person weekly due to our young children and my pain and anger returns each time. I wish I could get past this. I feel I need him to feel sorry or remorseful but he is happy and could not care less about the harm he has caused to three people he once loved.
