DEAR ABBY: I’ve been married to my husband for 30 years. For the past five years, I’ve noticed that he is acting a little different. He’s lost a lot of weight. I found out he’s been smoking drugs. He had this problem years ago, and I thought we had it beat. But now I’m getting the impression that maybe you can’t ever beat it.

My daughter gave me a tracker for my birthday. I put it in his car to see where he went, and it showed that he went to an apartment building and was there for almost an hour. I don’t know who lives in that building,
