Should I go on a third date with someone who after both dates said he felt no connection?

Guys are different than girls in the sense that they don't always immediately feel the emotional chemistry that women get when they like someone. His motives could be elsewhere but I think he's just a little confused. Tell him you want some time before another date, but in the mean time talk to him via IM or text messaging, maybe talk on the phone. If he asks again that means he at least has the desire to meet with you. If something like this happens again? Leave him be and keep on looking.
