Jacqueline says:

Dear Worry Wart,

You smelled perfume on him? Aren’t people who have affairs these days more discreet than that -- like taking showers before they go home? Maybe the reason you smell perfume is because a woman gave him a hug. I hate to think after almost five years, twice you “think you smelled perfume,” you jump to these conclusions. But I’m up for being upfront. Why don’t you just come out and ask him?

Dear Worried Wilma

I agree with Jacqueline. You can’t sit around guessing and obsessing over it -- it is a waste of time, is emotionally draining, and it’s not going to get you any answers. Besides, you may be fretting over nothing because your only claim to him cheating is that you smelled perfume on his shirt on two occasions. Nonetheless, it would behoove you to flat-out ask him and be prepared for his answer.
