My boyfriend lost his wife in June. She was shot by the man that she was cheating on him with. We have been dating for three months or so. He is just now getting depressed. He thought he was ready to move on but now he wants to take things slower. I understand that and he wants me to wait on him because he says we have a future. He says that this will make us stronger. How can I help him get over this depression before it comes between us
