I have been good friends with a female for 3 years. She is married. I am divorced. She and I would spend a few hours shopping or a day together now and then, chat on the phone, etc. Her husband made a sarcastic remark to me recently. I thought nothing of it until several weeks later when they moved an hour away. She does not contact me at all. I have texted and phoned and she has made no attempt at all to contact me. I did phone her once and we talked for10 minutes before she made some lame excuse to hang up. We are adults here 50-60.

I've quit trying. He might be so jealous he might hurt her or I.

He is most likely jealous, is her husband not included on the days out ? If not, not why? Is any group activities done that include her husband?

How much are you texting, how much time together?

If you message a few times a day, or if it was 50 times a day, makes a difference,

For whatever reason, it appears he didn't like her having a close friend. Perhaps he wanted more of her attention, maybe he doesn't have any friends of his own, perhaps they have some problems, financial, relationship wise, etc, that he was afraid she might discuss with you. It could be a number of things.

You could try sending her an actual letter letting her know that you miss your shopping trips and that since you are only an hour apart maybe you can plan to get together once or twice a month. Other than making an effort to stay in contact with her now and then, there isn't much else that you can do.

I'm going to make a wild guess that events have conspired to LOOK like they fit together when they don't at all.
He makes a sarcastic remark.
They move an hour away, WEEKS later.
Now she doesn't even want to talk.

There are so many possible reasons for what is going on. Moving is a big deal - different jobs, be near aging parents or grown children, loss of finances and a need to live more cheaply, on and on. All of those take up a lot of time. Chatting on the phone takes last place. And if the reason is financial, she may have to start finding ways to help bring in some income. If you don't have to work and have a lot of time on your hands, the husband's sarcasm may be based on the frustration of seeing how you live versus what is going on with them. And if they have moved somewhere where they are now close to family or old friends, those people are naturally going to take precedence over people who are now far away. C'est la vie. Let it go. Send her a card for her b-day and a holiday or two, with a little note.

It's also possible that you haven't given us enough details or maybe left things out. You say you would shop for a few hours now and then...How often is now and then? How many hours is a few? What kind of contact did you have between those shopping trips? Why was he never invited? He probably was jealous and maybe he had a reason to be.

Take the hint and leave her alone.

Whatever has changed for whatever reason, let it go, ad don't dwell on what was. Accept what is and find your own thing to do with new friends, that you enjoy. Adjusting to change is never easy, but that doesn't mean it shouldn't be done.

A big factor I did not see mentioned anywhere is your gender... male or female. Almost sounds like you are a guy by what you are writing, but the username indicates female.

I was ready to give an answer until I read "I've quit trying. He might be so jealous he might hurt her or I.". Why would you state that? Did she give you an indication that he's abusive? If not, why would you make that kind of a statement?

He might be so jealous he might hurt her or I.

Why would you assume this ? Is it you going to the extreme or you are not telling us something ? Why would a husband be SO jealous of two women shopping once in a while?
