My partner of fifteen years has got it in his head that I was cheating on him while working away from home. This suspicion came as a result of google history saying I didn't go home to my apartment one night I was away. I should also mention that while google timeline said I didn't go home, the entire nights snowshoe pings that clearly show I was in my apartment. The problem is that it has been six months since said night and my partner refuses to believe that I did nothing. He feels that my body language says otherwise and he has said really hurtful things around the topic. We are supposed to be getting married in March but I don't know what to do. If my partner truly knew me, he wouldn't have any doubts at all. I have never cheated nor would I ever. I have done all I can do to prove my innocence but now I'm lost. He is probably right about my body language but any change in it is mainly due to him watching and studying my every move and this is making me self conscious. Any suggestions would be welcome
