Trader, I don't know how much dating this guy has done in his two years without alcohol. Some people take it slow, so they can take the time to work on themselves internally. In all likelihood, he is probably very excited about the weekend visit in his own way, and probably nervous in a good way (not necessarily worried about relapses).
If you are sticking with your decision not to drink, and you are meeting at your house, then don't have any alcohol in the house. If you are meeting somewhere, then don't order any alcohol. Give yourself a chance. If you like him, smile into his eyes and enjoy it! I hope you will be comfortable and have a nice time.
Then after the meeting, give yourself a chance not to drink for another week and look at your thoughts about how things went in the last 2 weeks. I can't guarantee it, but you will probably have lots of things to say about how things feel different.
Hope it all works out for the best.
