My partner of 20 years thought I was walking the dog this morning. I wasn't I was having a lie down. I heard him in the next room say out loud to someone ,"I miss you, I miss you ..." and then I think he said the name Kat. My dog then made a noise so he came into my room. I asked who he was talking to. He was visibly shaken when he saw me but said he was talking to himself about me! He said he was embarrassed because he was about to look at porn. I don't care about him looking at porn but I know he was talking about missing me out loud. I have a 5 and a 9 month old girls. What do I do?? Ignore it and live a life not trusting him. Or leave??
