I'm in the exact same situation as you... broke up about 4 weeks ago and recently started dating again. The new guy doesn't drink at all. As soon as the date was over, I came back to the house in hysterics... to be honest, I think we need more time to heal.
It's very confusing, cause these new men seem too perfect, so why are we still hanging onto the past?
Wish I had some advice, but just know I'm here with you in the same position<3
