Dear Amy: I’m a widow in my 60s. A couple of years ago I reconnected with a former boyfriend from my teen years. Even though he’s separated from his wife he is still married and not planning on divorcing her.

We went on vacation trips three times, along with my brother and sister-in-law, who are also friends with him.

Six months ago, he sent me a text saying that he was flying to visit me for the weekend. I told him I had other plans and that I wasn’t available, and he went silent, stopped texting or calling, and didn’t answer my – or even my brother’s – calls.

This made me realize a few things: He is immature, he wants to be a priority, and there is no point in seeing each other.

Then, months later, I got an email from him, asking how I’m doing.

I don’t even want to reply.

Am I right in stopping this friendship?

Dear Wondering: An email asking, “How are you doing?” without any preamble, statement or narrative of any kind doesn’t inspire a response.

My instinct is that this dude gets bored and restless and basically trolls through his contacts to see what interest he can tease forth.

You have pointedly never been to his home (all of your time spent together has been on vacation trips), and so I think it’s likely that he cohabits with his wife and is playing the field with people who live remotely.
