I asked him if he’d been with someone else and he said no. The pictures look cozy but doesn’t mean he cheated.  But I can’t help thinking that he did. It would explain a lot of his behavior.  My partner has always been kind and loving too me up until recent months when he was distant and pulling away. I think I have to end this now. He originally asked for some space and said he wanted to work on things but I think he needs to work on himself.  I need to move on but I’m so sad and shocked.
