I saw picture of him and a woman (her kissing him on cheek) on the phone screen. I automatically assumed they sleep together - he told me he fucked up and went out with a woman on a date, but it didn’t go as far as sex. I told him I don’t believe him and if it’s true to show me his phone with messages from her, because otherwise I’m kicking him out. He said the conversation is private between them too and he is not going to show me, because he doesn’t want the message to go to third party. Am I being unreasonable ? I’m angry he would rather walk out than show me the messages (I told him I expect the worst-sexting and all so whatever he shows me can he only better or match my thought). He still refused ! What to do next
