My wife never sent voice text but I have kept all of her regular text. I go back and read them from time to time. They will never be deleted by choice. It'd been more than 3 years now. Her sister de-activated the FB account because it was too much for her when she was sent reminders about their friendships/birthdays and such. Sometimes I wish it was still up but I get why she shut it down.
Sorry for your loss. That has to be tough.
