New here. Confused, broken down, hopeless.

My ADD husband has made me start questioning myself and my own needs - his rebuttals are often off topic or specific to one tiny literal detail of a conversation. I am going in circles in my head - am I making this all up, overreacting, crazy?  Do I need to continue to be accused of an affair (which is a ridiculous notion) every time I make plans with friends?  The only time I do anything social (he refuses) or for myself?!?  Do I need to constantly nag him?  Do I need to drop everything to help him find his wallet or phone for the 5th time this week?  Do I need to explain how he can be a million miles away when he is sitting 5 inches from me?  Do I need to continue explaining how pricing up on social cues is his responsibility and its not mine to itemize all the things he could do to help out?  Our conversations/arguments get us nowhere - there is grey but he sees only black and white. My family and even his have expressed concern for me and our two young kids.  I have no steam left. Hanging by a thread and feeling shattered. He wants to go off mess and says I am the one with the issues. He actually just asked if I was still in love with him....I don't think I am anymore.  I don't know what to do anymore. He sends me text after text and email after email- won't talk face to face. Starting counseling next week but I think it's too late. Just want my kids to make it through this - I am tough but they might not be...
