Having some major trouble with my life? Wife is very suspicious of me. Thinks I have a gal but I just like otb

Open communication. I am guessing that you spend a great deal of time away from home given the time demands of otb. Your wife is free to interpret your absences in any way she wants unless you give her comfortable reasons to think otherwise. Might you invite her into the otb arena as an option, which would explain your absences? Otherwise you have to somehow improve communication to restore the trust.
