I think when last church was talked about you said that you would go for X number of weeks, because consistent attendance helps with socializing, which was a goal of yours.

If you have not reached X number of weeks, then I would encourage you to go. Not because you "should" go to church, but because that was your commitment to yourself, to help with socializing.

I support you either way though.

With regard to the guy, I think I might be saying the same thing as golden_eve, but just to be sure: if you meet him for coffee and you like him and are attracted to him, then I would advise against sex with him. Sex can tend to make you like him even more, and then there will be a good chance that you'll be wanting emotional closeness from someone who isn't prepared to give it.
