<human>: I actually posted a few weeks ago when I was starting to get suspicious but I can't find the post. My husband and I have been together for about 4 years total. A few months ago I started to get a bad, suspicious feeling, but I don't know if I'm just being paranoid, and I don't want to make accusations out of nowhere.

My husband usually works in the town we live in, but one day a week, he goes to a different office in a town about an hour away. On the days he went there, that's when the suspicious behavior started. Every single time, he would have some excuse for coming home late. His boss wanted to hang out after work, his GPS took him on a really weird route, there was construction that made for really bad traffic. It was all plausible but I just had a bad feeling about it.

I never said anything to him because there was really nothing to say.

He left today for a business trip. And I just am sitting here at home by myself wondering...is he really on a business trip?

Even if he is on a trip...he could have a one night stand and I would just never know. 

I can't tell if I'm being a crazy person or not. How do I confront him on the basis of nothing? What do I say to him? Or should I just tell myself to stop worrying about nothing?

Give me a shortened version of the text
<bot>: Husband keeps having things come up that keep him out/away from home and I feel suspicious that he may be hiding something from me.
