I have never experienced cheating, but I have experienced an almost cheating sitution paired with lying and sneaking around... In that situation I tried and tried to get over it, but the trust had been broken either way. I had to move on. Once my trust was gone so was the foundation. I had to shut my emotions off completely which in turn made me ask myself " If you dont trust this person and now you have non emotional attachment why are you here"
I have since moved on into another relationship
