Maybe some social events that don't involve bars/clubs? I completely get the "social lubricant" and empathize fully but maybe if it were a booze-free situation, it might take a little bit of pressure off of you. Or maybe a "mocktail" so you have something in your hand.
Other than that, I assume that if you've been sober for over two years there's a reason (as stated - hiding out at home and online, drinking progressively, turning things around) so it seems like a bit of a tragedy to toss it away like that. You could check out the social news/opinion website, reddit(.com), and look through the "AskReddit" section as I recall loads of Q&A posts regarding everything from alcoholism to how to meet potential partners and everything in between throughout the years.
Best.
