Venting

I don't know if I can trust my person again he did something that has me question everything he does and I cant be relaxed i kept glancing over at his messages nd got all upset nd didnt want me to see his messages now I'm thinking he may or may not be hiding something idk if I should continue thing with him we are married and the friend he is talking to is the one guy who gave a girl his number back when we decided to work things out we weren't official yet but the girl message him months later when we were offcial nd he said he called it off cuz he didnt feel right

I dont think his story makes sense

He said they didnt talk much just that one day that she messaged him nd he felt he was doing something wrong to se called it off be if nothing happened what is to call off right like they exchange named nd he said she was from Houston how does he know that nd if the friend gave the number to her awhile back nd he calms he forgot all about it so how does he know that stuff I found out he was texting her in November and there were messages deleted I could tell then the next day he deleted the whole message from his phone
