I'd say give it another chance, however, you closed him for a reason, so be alert with that.

I closed a match coz it usually takes him one week or longer to respond to my email, I think he's not interested. but after he sent me "potential" request, I reopened the match, talked with him, met him, went out for three months with him, and ignored the "not interested" "not emotional available" signal he was sending me from the begining and ended up being hurt.

so will I reopen this match if I've had this experience? absolutely no. It's good to hope for the best, but it's also good to know whether you two are good matches and avoiding wasting time with the wrong guy.
