My husband's sister died two year's ago and her husband is getting remarried. What do I call him now when I introduce him? My ex-brother-in-law?

Call him your friend

If they weren't divorced, I would refer to him as your sister-in-law's widower.

I would just call him by his name, continue to call him your brother in law to honor a decision to continue to consider him a part of your family, or introduce him as a friend. If you feel explaining the relationship to the person who you introduce him to is important, clarify it later when he is not present.

LOL, I can't help laughing, sorry.
:D
Mmmm, I think I'll call his first name, that's it.
No need to tell people your relationship if that reminds anything sad.

I didn't see anything funny about this question.

Continuing to call him your brother in law would be fine since he does have a link to the family.

Calling him your brother-in-law is a sign of resepct to your husband's sister.. Using his first name is also fine and you can explain the relationship later. He is still a part of your family and that is what counts most of all.
