You should not have to go through this. I understand your husband is depressed but still it is no excuse for act this way. When I am depressed I turn to my boyfriend for help I don't turn to another man. I may also turn to my family for help but never another man. I say let the other woman take care of him. You and your son don't need this stress on you two. I understand you love your husband but sometimes you just have to say enough is enough. If you keep letting him have this emotional affair with this woman and don't put your foot down and say it me or her you will never feel better. If he said he doesn't love you anymore than it is time to let go. I am sorry if none of this is what you wanted to hear I am trying to help.
