Help! Major problem!?

So, my friend introduced me to this guy a couple months ago and we kept in touch by facebook only. A couple weeks ago, she invited him to a party I was attending, and the only reason he came was because he knew i was interested in him. At the end of the night, we werent drunk but not sober either and made out and everything. The morning, when we woke up, we didnt really speak and we havent spoken since (our only way of speaking is on facebook chat). I'm tired of waiting ( I've been waiting for like a month), I want to inbox him to know if he would like to see me again, etc. So...what should i write??
