Is it me or is my former "friend" just totally on something?

( Alright I will admit this is quite long.. So hang in there...)A little while back, I went to this little party, with a former friend, who didn't want to go by herself so asked me to come along. (Which mind you I hadn;t seen in a while) On the way to the party she talked about how badly she wanted to get laid and hookup with the host. She called first dibs on him which to me was no big deal. so after a long night we left and she had the most dissatisfying look on her face. I admit I had fun with the guys, but I definitely was NOT all over anyone or wild 'n out. The guy she wanted to hookup with didn't talk to her for the whole night. Nevertheless I asked this "friend",(not knowing how she felt about him) if it were ok if I messaged or added the dude on fb. She said she did'nt care so I went on ahead and did. After replying to her statuses a couple times, this one time I ended up talking to another guy I met at the party through her wall. And I guess she mistook the notifications as me replying to her. eventually later i replied to another status, and she told me to leave her alone. I thought she was joking but she was serious. Some other dude commented on my post telling me I was annoying and : "just couldn't except the fact that I"m annoying". I of course cussed this dude out cause he didn't even know me! Then eventually the former friend told me I was embring myself and needed to end the convo. Like what the hell?! I had no idea what she was talking about. Until finally she told me it was because I made her "look bad" by messaging the host of the party. All I had done was thanked the guy for having me over, and put a joke at the end. Which with what the joke was pertaining to I doubt he even knew what I was talking about, he was extremely drunk! Anyways the this former friend tells me this and goes on by saying,:"you're super annoying and you made me look bad! You need to learn some shame virgin!... If you can't handle that, you can suck on..." I mean what the hell was that?! Did she want to get laid that bad?! My god!!! And then afterwards was when I totally thought she was high. she texts me and says:" I'm sorry if you're upset but that's just how I felt. I'm not trying to start anything, I just hope we can agree to disagree and put this behind us." All I could think was WHAT THE HELL! I still had know idea what her problem was but I'm uming (and Lord knows I hate to sound vain) she was jealous at the attention I was getting from the guys because I got along so well with them. All she did was sit around and play with the house dog. She was a long time childhood friend of mine, that totally hurt my feelings. I had done nothing wrong and she talked so incredibly harshly to me, all because of one guy....
