I'm really struggling right now and need help to get clarity and would appreciate any words of wisdom.

My husband and I have been married 10 years, we have 3 kids, the past 5 years, I've been a SAHM and he's worked a very demanding job. We've seemed to have a pretty good marriage- I've always been devoted to him, he's kind and caring, a great father, etc. We have a comfortable and enviable life together.

However, for a little more than the past year, I've just had a nagging gut feeling that something has been off. I've never thought he'd be the kind of person who could lie to me or would cheat on me, but now I'm not so sure. Well, this gut feeling has festered, being ignored, and now I am having full on anxiety about my suspicions- like, I'm to the point that I am paranoid, always on high alert around him, and I can barely function/get through daily tasks.

I don't know if I should try to just deal with my (possibly irrational) emotions or if I should just tell him about my anxieties and insecurities and simply ask him, point-blank, if he's been unfaithful. What do you think? Ask or not?
