I'm going to cause a scene and think my husband is cheating.
Do you have any proof that he is cheating?
Yes, I've noticed that everytime I leave the house he would turn off his phones.
If you are sure that is what is going on, you should definitely confront him and not hide your feelings away. I understand why you would feel upset.
Nah, I'm going to find him red handed and I'm going to be right there to punish him.
While it's understandable to be jealous of your partner, taking revenge on him isn't the best answer. If you don't want to stay with him, then compile your evidence of cheating, file for divorce and let the courts handle it instead.
