Just to give an alternate viewpoint.. In my case, I was the one who wouldn't quit analogs. My husband smoked his last analog on New Years Eve. He made it for 2 weeks, silently vaping away while I continued to smoke around him. I had no idea how he did it. He would hand me one mod after another, "try this one" with different juices, "this one is pretty good" and over and over again, I was NOT impressed. After those 2 weeks, he started slipping little snide comments in whenever I'd come in from outside, "enjoy those coffin nails?" It was obnoxious.. I was living with THAT ex-smoker! (and don't get me wrong, he's an amazing guy.. he really just thought he was being cute)
After he was analog-free for an entire month, I started asking a few questions here and there. Little did I know, he was on ECF badgering anyone he could find to give HIM tips to help me make the switch.
One Saturday afternoon, we were sitting in the bedroom talking and he was vaping. We were planning to go to a friend's house that night & he had his ICON (with his AVE Gorilla Juice) and his little eGo (with AVE Hype) all ready to go. I knew I didn't like the GJ, but I hadn't tried Hype. I asked a few more questions & then I decided I'd give it a go. I whole-heartedly expected to be smoking analogs that night. We got to our friends' house (also smokers) and they used their ecigs while we played some poker. I got up and went outside with them 2-3 times and then just decided that it didn't taste nearly as good as the Hype I'd left inside.

I smoked my very last analog at 10:30 that night. Three days later, my friend ordered her eGo=t and she hasn't looked back either. We're still slowly encouraging her hubby now.
The bottom line... just keep doing what you're doing. Try to find some juice that you think he *might* like & keep it handy for him. But he won't do it because you want him to, he'll have to make the choice on his own.
I will say though... as the "smoker" living with the "ex-smoker" I did NOT feel real proud of myself. We had both smoked for around 16-17 years and I always vowed that if he was ever able to quit, I would NOT be that wife who tempted him with smoking again.
I sort of find that funny now... but now I understand HOW he was able to keep from lighting up again while I was still smoking. Vaping is just so much more enjoyable!
Good luck!
