If you die, are you no longer married to your wife/husband?

No you are still married, unless you file for divorce papers that is. Chistianty suggests that each religion is a pathway to god, regardless of what religion you are, God gives immortality which means is you dont get a divorce and you die also, you shall be reunited to your other half in heaven

Until death do you apart.  Simple. You ain't married anymore.  You wanta get re-married, go ahead.  There are no marriages in heaven (as the angels), all will be male gender, but no sexes, no marrying, no dates, no buying flowers or candy, no anniversery presents.  The only Bride in heaven is the Christians married to Jesus.Hope I didn't ruin someone's day

Yes, no longer married to your wife/husband.

If you die you are still married but you still can get remarried.

Legally you are no longer married and are free to remarry, or date, or whatever you want to do.
