Wife suspects husband didn't vacation Las Vegas by himself

DEAR ABBY: "Darrel" and I have been married 28 years. I thought we had an easy, comfortable relationship.

We have no children; it's just the two of us with a large family of furry animals. We don't take vacations together because one of us has to be home to care for the animals.

Last year Darrel took four trips to Las Vegas - two for business and two for special sporting events. I'm beginning to get little nagging signals that he may not have been on these trips alone.

He shuts his phone off for hours at a time and changed the password on his computer after I had to get on it for a security update.

The last time he went, he told me he had won two tickets in Las Vegas to a show, so I asked him to bring the extra one home so I could see it. When he returned, he didn't have it. He said he had misplaced it.

There are other things, too, and I don't know what to think. I don't want to hurt his feelings if there isn't anything going on, but I need to know.

What do I do?

DEAR WHAT HAPPENED IN VEGAS: If your intuition is telling you that something is wrong, listen to it. Tell Darrel you're feeling insecure and why.

Start going with him to Las Vegas. Hire a pet sitter if necessary. It will be money well spent.

If your husband isn't open to it, hire a private investigator to tell you what's going on.

Clearly, something is up.
