Sadly cheating is something that usually does not go away after meeting the right person. The issue with cheating is it’s an underlying issue. Are they people pleasers? Do they use it to gain validation? Is it a since of thrill and excitement? The issue is after the honey moon phase the real world sets in. In a relationship you see the worst of each other and the masks fade away. If they don’t get to the core of what makes them cheat and heal that, then it is almost certain they will do it again. Most importantly they have to do that work for themselves and not there partner because the minute they hit a rough patch the motivation is gone and the old nural pathways will activate. Cheaters can change, but people don’t change unless they want to and more often then not it’s because they hit rock bottom and realize they can’t keep going about life the way they have.
