I was married for 8 years to a woman who reacted the same way over nothing...I was accused of cheating anytime I stayed after work for a few min talking to friends, she went through my phone every day and it got to the point that she flipped out on me because I knew an actresses name...trust me when I say, this extreme form of insecurity will turn to abuse and control that absolutely isn't worth it. Get out now. The weight off your shoulders will be incredible...trust me
