My husband is constantly looking for evidence

Hi Coach
My husband is not doing this work but I can see how in his head he is constantly looking for evidence that I don’t love him. Every little thing I do gets commented on from a very negative perspective. I try to stay calm and non defensive but it is very draining to constantly be told that what you are doing is wrong and being questioned on my motives (as though I do things deliberately to upset him). I am not sure how to change this dynamic but something needs to change as this isn’t fun for me. TG that I am building my self confidence up this month in SCS as I need it right now.
