Probably too late

Yes - I know it goes against everything you may be wanting or feeling right now, but yes, DO NOT contact him.

Get that letter, keep the original and make a photocopy or two.

Get a notebook and start documenting things. Websites where he's logged in (print a screen shot), things he's said to you (with dates), cell phone records if you have them or can access them, dates of those other 'no cell phone service' trips etc.

I am only trying to prepare you for the possible worst - he is very likely in a relationship with someone else and I'd be real suspicious of the no cell service excuse (seriously, does his work take him to oil platforms in the middle of the ocean, remote archeaological digs, deep underground? Not being flippant here, but you know what kind of work he does. Does that excuse hold water to you?).

If either one of you files for divorce, you will need your logbook and a copy of that letter as evidence of marital abandonment and (possibly) adultery. Any other evidence you may have that he tried to fake his own death should go into the logbook, too.
