The I love you date

Against my better judgement, I went out with Auburn again. I knew I didn't like him, but thought it wouldn't hurt to give him another chance. I knew it the night wasn't going the way I would like it when Auburn asked me on the way to dinner what my biggest insecurity was. Hello, I don't know you and this isn't 3rd date talk. I only talk to my therapist about things like that.
Throughout the course of dinner, I tried to be talkative and lively, but the insecurity question threw me for a loop. I didn't answer him...I feel like that was a very personal question and call me guarded, but I am not going to point out my insecurities or flaws on date 3. This further proves my theory that Auburn is desperate to find a wife and is not looking to date someone.
After dinner we went to one of the newer restaurants in Atl to grab a drink. Auburn had a friend coming into town and wanted to meet up with a few friends after dinner. I was fine with this because I was tired of the serious therapy talk.
We were by ourselves for a while at drinks and I noticed Auburn was pounding the drinks. I was 1/4 of the way through my gimlet and he was on drink #2. This is where things went downhill. I am all for constructive criticism - I would love to hear what I do wrong on a date, but the following is not the preferred method.
Auburn: I find you attractive and am drawn to you but don't know if I am going to like you because you are too quiet for me
Me: Really, I don't really know you yet but once I get to know people, I can assure you that you won't describe me as "quiet"
Auburn: No, you are too quiet for me - I can't always carry the conversation
Me: Maybe it's because you ask super personal questions that I don't want to discuss or elaborate on
Silence...
Auburn: I don't think you are in to me
Me: Why do you think that?
Auburn: Because we haven't had sex or messed around
Me: What?
Auburn: Well, it's our 3rd date, we should being having sex tonight and we haven't even messed around
Que the friends...
I decided I was leaving and taking a cab home at this point but his friends talked me into going to the W with them under the presumption that it would be easier to catch a cab from there.
So, again, against my better judgement, I went with them. By the time we reached the W (only a block away) Auburn could barely walk and even his friends were suggesting he drink some water and take a break from drinking.
I was tired, sober and totally turned off after the sex conversation so I informed the group I was leaving.
Auburn: Why are you leaving?
Me: I am tired and ready to go home. Please stay out with your friends, I don't mind grabbing a cab home.
Auburn: No, I want to go home with you.
Me: It's ok, stay with your friends.
Auburn: Let's go home together.
Me: No, I am going home by myself!
Auburn: my name, I think I love you
Me: Mouth on the floor.........
Auburn: Did you hear me, I said I think I love you
Me: turn to friends and tell them I am leaving and I run

1) who does that? 2) I don't like the 3 date rule. Everyone assumes if you go out on 3 dates it's an automatic pass that you are going to have sex. Maybe that is what went wrong with BDE. I am not into this...I don't think I am a prude, but good Lord, I am not going to sleep with everyone I go on 3 dates with. If this is the rule, I am going to have a lot of disastrous 3rd dates.

Auburn called the next morning and left a vmail - "wanted to catch up, sorry about last night, I was a little drunk. Give me a call"

I hate when guys don't call me back so I know the right thing to do is call him and tell him that we are looking for different things in a relationship, but I dread it! Tomorrow I am going to do it.
