Need to vent !!

I am a firm believer that men have their own "PMS" each month so I try and let my DH be angry and moody when I realize that is what is happening. He literally is not a moody person. Anyway, last night when I finished looking for something online (that he asked me to) I noticed something was bothering him so I asked what was wrong. In the mist of this argument ( which was because I was online too long then turned into me not paying him any attention) he accused me of cheating!!!! uURRGGG! We both have been married before and his ex cheated on him. I get it, he has been hurt before but I am not her!   Ok thank you for reading my vent
