Can you say "Awkward?"??

Today, I did Coffee at church. I love doing coffee because people have to come to me and talk to me, and it is an easy exchange with the starting topic of... coffee. Anyway, it is about the only time I feel plugged in to church. But something happened today that was way out there in my book. This guy, Frank, is sort of a d0-it-all maintenance guy, came over to talk to me, and basically harass me for being late. This is a regular occurrence, because it is usually he who gets the coffee started because I am late getting there most of the time. Usually it is just a little banter then it is over, I move on to talking to others & making coffee. Today was different. He hovered today, kept coming back over to talk to me. He asked more than once of he could help me, but I really don't need another person in there, it's a tight squeeze as it is. Plus I am faster on my own. So, I politely decline each time. Then he asks me if I am a Facebook or My Space person. I tell him Fb. He asks if he can be my friend on Fb. I said sure! He said, you know I should get your number, I didn't think anything of it at first, so I gave t to him, thinking that I really do need some friends. Then he asked what things I like to do. Next, he says we should hang out sometime. I'm like, sure.... Ok, I really thought he was married this whole time I have been coming here. I knew he has 2 kids, and I thought I saw a woman with him before, but I guess I don't know anything for sure. So, the next time he came around, I checked for a ring, and was dismayed to not see one. He kept saying things like, so you think it is a good idea if we do something sometime? It started to dawn on me that he isn't looking for a "friend", he wants to date. So, about the third time he asked if I thought it was a good idea we hang out, I made myself say something. I do NOT want to lead anyone on, and you can probably guess I wasn't loving this attention from him. I said, what are you looking for, because I am just looking for friends right now. VERY awkward to say the least. He said, well yeah friends then we see what happens. He got pulled away then, and I slipped out of church as fast as I could. He called me on my way home, and apologized if he freaked me out, and said I could call him sometime. Now what am I suppose to do? I wanted to be connected at church, but this wasn't part of the plan. He is very much a part of things at church, and is at everything. This doesn't help my current feelings about going to church right now. What do I say to him??
