People will justify most everything they do, especially if it is something most others will view as wrong or improper. I knew a woman years ago who was in a most abusive marriage, met another guy, began an affair with him. I think it saved her, he gave her the courage to leave her husband who basically said he would kill her if she ever left. She had been through so much for years Right or wrong, the affair saved her, mentally and physically too. People might say, she should have left hubby first, but she was literally scared to death of him and what he might do.
