Can't read the signals

Background info; Im 28yrs old and live in northern florida. My guy is 33 and lives in miami (about 2.5 hours from me). We have known each other for about 6 years, but havent seen eachother in almost 2 or 3 years. We've never had sex. So, this guy that i've known for a while calls me on Thursday late night and invites me down to Miami to see him for the weekend. I hadn't seen him in a long time and it was last minute so i didn't know but, he basically convinces me to "be spontaneous" and I agree. I drive the 3 hrs. down Friday night and get there around midnight. As soon as I got there he was a perfect gentleman. He got me a drink, gave me a tour, we even went for a walk around his building and just talked. Went to bed that night and made out a little but he ended up just holding me the whole night. Next Morning... We fool around a little bit that morning (he gets his, i dont, but he gives the promise that later there will be sex) and he makes me breakfast before we leave the house. I happened to be standing behind him while he was browsing his facebook and notice he's looking at all of MY girlfriend's pictures! (I think its alil weird but shrug it off cuz i look at pictures too and hes not mine to get mad about him looking at girls, but really? my friends?) The whole time we are out he keeps asking random questions, like "why are you single? what's your perfect guy? what motivates you?" He makes little comments about how he wants a good girl, he wants someone that he knows, he doesnt want to meet someone new. He even says "what if i asked you to be my girlfriend right now?" We spend the whole day having what i think is fun together. We went for a walk on the beach and everything. He pays for everything too, even to park my car for the weekend. We get back to the house and he says that he has to go out to a social/business meeting last minute and will be back. (His job is like that so i know it was legit) he got back at about midnight (2 hrs later) and we watched a movie and went to bed around 4am. He held me again all night and caressed my back the whole night. The next morning we fool around again (this time i notice he has a condom by the bed, but we never actaully have sex.) By the time we get up he is a tiny bit distant. We talk for a little bit and he makes the comment that he has another meeting so if i want to leave early to head back home that's "cool". He says that he's really sorry he didnt mean to have other things to do, but that it was last minute and he didnt really plan. He says next time he will plan it much better and that it'll be perfect. So i get dressed after a little while and basically he walks me to my car, gives me a half hug and we part ways. After i got home we talked on the phone for a minute and he again says that next time i come down will be better. I make the comment about how we didnt have sex and he says "sex is more about a connection for him now and that we have a connection but that we just hadnt seen eachother in a long time" So now, im here the next day trying to sort through all the signals. My basic questions: 1) Why did he invite me down for the weekend if he knew he had things to do? 2) Why promise sex repeatedly, do other sexual things to each other, but not actually have sex only later to say "its about a connection" 3) Should i be worried about him lurking on my firends picutres? Is he prospecting through my firends? I feel like maybe the basis of the whole weekend was him trying to guage where my head is and all relationship wise. I think he likes me and wants to see where we go, but that maybe the weekend was a litte too unplanned and he panicked??

No I don't have a bf. this guy is the only one I'm talking to.

Hi he sounds lovely and I think he does really like you. A person wanting to have a connection before sex is a mature one ,and means he does not want to use someone and least of all you. You obviously have chemistry with each other to be friends for 6 years. As you say both of you have not spent enough time together to make a choice on much. Hang out as friends do fun stuff together with no pressure...... if it is meant to be it will work out...
