Tricare is something I know about and this is wrong. If you are married to a military retiree your benefits never expire unless you remarry.
Now you card may expire, but that does not mean the benefits have, you just have to go to a base or armory and get a new card.
This article is confusing (no surprise, MSM).
It says the husband “separated due to an injury” from the army with 13 years service and would have Tricare for 6 months afterwards.
