I would say that it would be very beneficial to find out exact reasons why he left, and what was the "major event" that makes him want to return. Based on those answers you can likely tell if the relationship is worth salvaging.
For someone raised as a witness, the pressure to get baptised is extreme. The fact that he avoided getting baptised is a big point, it would be best to find out why.
For yourself, I'd suggest getting the book "Armagedon Delayed", "Crisis of Concience" is a very good book, but it will be a very dry read for someone not familiar with the teachings of the Watchtower. For Witnesses, it is extremely powerful because it give insight into what goes on behind closed doors in Governing Body meetings, that is, the leadership of witnesses.
You are very correct though, he's pulled the rug out from under you with this recent revalation and that's not fair to you. You may notice behavior changes as his mind starts to revert to witness thinking. You may notice two seperate personalities. The man you knew and loved is still there, but he may also have a "witness personality". When talking about religion, it will be a different person. Unwilling to talk and reason, constantly changing the topic when challenged, using alot of witness lingo that you will discover here "sign of the times", "worldy", "elders and brothers", "wicked system of things" etc.
If he's said no sex until you get married and that's a year away, that's completely unfair. My question is, did he ask you if it was okay, or tell you that was what was going to happen? If he told you, that's typical witness mentality. He is the head of the house and that is what he sees as the correct spiritual thing to do. Your opinion doesn't matter because you are woman, a "weaker vessel". Instead, if he asked if you would support his decision, then there's hope for him, but it's a tricky road.
