The case of the so-called "cuddle buddy"?

About 2 months ago I started seeing this guy, it seemed like a really good connection at first. Hes thoughtful, considerate, really great to look at and most importantly funny. Pretty much from the moment we met till now we've been hanging out every weekend, going out to dinner or other fun things (weekend getaways, moonlight cruises, nightclubs, sightseeing). Most recently he took me out for my Birthday, we had a great meal it was a pretty romantic night and we finished it up with a bottle of wine and a movie..when the movie was over and the wine had stopped flowing we were cuddling in bed when he said to me, "I know you want a boyfriend out of me, but I'm a fickle one, so your gonna be my cuddle buddy - got it!" and then he playfully slapped me on the *** while I laid there pretty much feeling like had twisted a knife in my heart. I didn't know how to take this, after thinking things were getting hot and heavy I reasoned it was all in my head and perhaps they were fizzling out. I completely backed off, my Birthday was on a Friday and we had plans to hang out all weekend but I decided on a whim that Sat. afternoon I was going to head back to my hometown and be with family and friends. Within hours of me being gone he began texting me "Hey, I hope you have a really great time with your family, miss you honey." This sort of annoyed me as I felt he was sending me mixed messages. I didn't even respond, which then prompted him to send me like 5 texts when I was on my way back home on Sunday..needy sort of "talk to me" type texts. We had some back and forth banter..again with me being friendly but frosty due to what I perceived as a clear indication on his part that he wanted space. So the following week he was due to go to a friends wedding out of town and he called me about two nights before he left and asked if I'd come stay at his place, I lied and said I was busy and asked if we could just play it by ear to which he asked if I'd come spend the following night. I did. When I got to his place he proceeded to give me an "extra" key to his apartment and told me I should feel free to stay there the whole week seeing how its closer to my job and would be a lot more convenient for me..so he pretty much just gave me his place, no strings attached just so I could hang out and avoid a considerably longer commute. I have to say I am sooooo freaking confused, I'm not sure if this guy is into me or not..and here's the thing in all the time we've been dating, we've still never been intimate. That's not my doing either because honestly about a month in I was inquiring as to when there was gonna be some hanky panky to which he informed me he just hasn't been horny for awhile and hasn't felt any desire for , however I've seen him on several so called "dating" websites though out the course of our courtship and I figure there must be some kind of drive there..so I wonder how true the whole I'm not horny thing really is. The one time we did come close to was on a drunken night home from the club one evening, where the mood was kinda shot when he in a "drunken stupor" pissed himself in the car..it kinda killed the mood to say the least. I like this guy and would be up for continuing to see him but I just get that weird nagging feeling that something isn't right..he's like the king of mixed messages. Why would someone have a whole "cuddle buddy" speech with you then proceed to give you the key to his house, and text you like a mad man the minute you start giving them the space they were hinting towards? He's called and texted me a bunch of times from his vacation, most recently tonight - just to give me a run down of all things he's been doing and to reure me that the only person hes been spending time with is his sister..why is he bothering to tell me all this if I'm just his 'cuddle buddy', that would seem to indicate that I'm not owed any kind of explanation about his comings and goings. Am I being paranoid here, or should I just continue to take it day by day and hope that I'll at least leave this having had a little bit of pion in the bedroom and perhaps more then cuddle buddy status - or is it just time for me to head for the hills? I'm really confused about this situation and could use all the advice I can get! Thanks in advance for taking the time to read this and for any insight you may have!!
