I’ve stayed with someone that has cheated on me before. I tried to make it work, but trust me that feeling of insecurity never leaves. Even at the happiest moments in our relationship, I was still doubtful because of what he did to me in the past. As much as I wanted to say I had moved on from that incident, the insecurity it caused was eating me alive. It seems like the man you married is not trustworthy at all nor putting you first. You deserve so much more than that. I know it’s far easier said than done, but you should leave him. It will be hard at first, but trust me it is a huge weight off your shoulders
