Hi Kristie
All marriages go through rough patches but what you are going through sounds really tough. One people live separate lives for to long it become much more difficult. Do you feel like he is trying? Have you guys talked about if the two of you want to be together?
I don’t know what the outcome will be but I think your best bet is to have a frank discussion preferably with blame put aside to answer If both of you want to put in the effort.
I truly hope things work out, but in the end make sure you look after yourself and your needs.
