Sober dates don't have to be weird. But whether you never touch things or just take a break from alcohol, there's no reason for that to ruin your dating game. It depends on why and how they act about it. Overall, I think that if someone has considered quitting drinking, it's probably a good option for that person, at least for a while.
I usually see it as evidence that they probably had a responsible conversation with themselves at some point. Dating someone who is sober has a lot of perks. Your first kiss doesn't happen because of liquid courage; it happens because of your own courage (even if your partner is drunk). Not drinking forces you to be more courageous and to make things happen, a good skill to develop in life, period.
It's much easier to give clear sexual consent. Evaluating if you really like a person is easier, since you answer all the questions about a guy's personality. There are no drunks texting exes, so there's been less drama for me and maybe a little less action, but I'm okay with that. I have the power and I choose it.
But I decided that this was an opportunity. Oh, you should, we could do one together. Gather stories for your friends. And you see how much people change when they drink.
It's a lot of fun to interact with drunk people until they reach a certain point.
