When you have a spouse that’s cheating, it can be completely overwhelming because you don't even know where to start. The questions to ask. Your heart is hurting. You're scared. There are so many emotions that go into that.
When a married person with strong values winds up in a limerent relationship with another person, it leads to cognitive dissonance. In that state, the person is emotionally and mentally miserable because their actions are in disharmony with their beliefs and values.
You suspected it long before you knew it for sure.Your spouse changed but you couldn’t quite explain the changes in a way that seemed to make sense to anyone else. You thought that you were imagining things, being insecure in thinking your spouse had someone else.
