We have heard about serial killers who are these serial cheaters? So spouses /partners who cheat because they lack the maturity to have impulse control, and they never should have pledged marriage in the first place, they are serial cheaters. If this was a pattern during the dating relationship, breaking up because of an other woman/man and then getting back together, the pattern will surely not stop because you take marriage vows.
One person cannot do enough to make another person change. Change has to come from within, and that person has to want to change. This is one area when many spouses think, “If I had only been prettier, or sexier, or more something, they would not have cheated.” However, that is not the case. It’s the cheater’s issue, not yours.
So if you are a victim do not think that its your fault because if even you would have gifted with every best quality /appearance it would not have changed a thing.
So if you are victim stop blaming yourself because the cheater took a decision to ruin the marriage or relationship and not you.
