You might as well put me in the psycho ward

I just confronted LR about Saturday night and not coming home and hearing he was with another woman and about the third person telling me she knew he was cheating on me and didnt know how to tell me. He says it all not true and that he has been true to me and that I just listen to what I want to hear. Man everyone must be against him. The funny thing is none of these people know each other. So how can they all be out to get him. But all he does is repeat that he hasnt done anything. PLEASE SOMEONE COMMIT ME NOW BECAUSE I AM NUTTS.
