I am a TERRIBLE judge of IOI, and -always- misinterpret things.

Just need some tips on escalating this. I was AFC about 5 years ago with her, we were always 'just friends (for about 3 years)', but I had no game. She is now 25, I am 27. I contacted her again through Facebook and made her laugh with some ridiculous/silly pictures of me I had laying around.

I invited her over last night (she is also good friends with my two brothers, so she wasn't just coming to see me). Here is how it all went down:

I called her and had her meet me, I picked her up at a location. She was hungry so I took her to a restaurant and called my brothers to meet us there. We arrived first so I had about ten minutes with her alone. Waitress recognized me and immediately said, "Oh you've got a girl with you today huh?". Girl im with laughed and said, "ITS NOT A DATE!!". She actually re-iterated that statement several times throughout the night, and I would challenge with "Oh it's a date alright, I bet you haven't done this in awhile have you?". She ordered a glass of wine, I ordered a beer and some appetizers. My brothers arrived and we socialized, laughed, caught up on old times. I took the tab. At this point she was supposed to go to school, but she said, "Maybe I should just play hooky and go hang out with you guys!". I knew there was no way I could isolate her because my brothers had not seen her in a long time either and it would not work.

On the way back to our house, I said, "I'm going to X location this Friday, they have amazing nachos there, what time are you available to go?". She responds with, "It's not a date right? Are your brothers coming?". I respond with, "It's definitely a date, and im pretty sure they wont be coming". She was adamant in constantly repeating, "Its not a date!". I have done a little bit of kino by this point, just innocently pushing against her if she was messing with me or if im directing her on where to sit/stand.

At the house I give her a mini-tour, she focuses on saying that she loves the bedroom and wish she lived there, and 'awww' how much I 'loved my cat'. My ex moved out 3 months ago but still has a lot of her stuff still in the house because she hasn't removed all her items yet. My female friend would constantly make comments, "Are you SURE your ex still doesn't live her? I can tell she was here recently, there is some mail here with her name on it!". I would respond with, "You seem to really be bothered by that aren't you? Are you worried that she might still live here?". She would respond to that with, "I bet she is going to come over any moment and KILL me!"

We all grabbed beers, exchanged stories, discussed old times and old relationships, while playing a board game. Kino was awkward at this point with my brothers in front of me (And they were flirting on her hard too), but I used different opportunities to touch her hand, shoulder, etc to get her comfortable. She was sitting next to me with my brothers sitting on the other side of the table. I made a few social mistakes in a couple things I said that I could tell made her roll her eyes in the, 'Oh, this is why I never dated this guy' kinda way. Overall though, she was laughing hysterically throughout the night and having a great time.

As the night got later she said, "Well I need to get home, can you drop me off at my vehicle?", and I grabbed my coat. On the way out to my car she again said, "Are you SURE there are no girls living here??". I continued to play around with her with like, "There could be, ya never know!".

As we drive back to our meetup location, she says things like, "Oh you live so close to my school, I should totally move in with you guys!". I respond with, "There's no place for you to sleep unless you want to share my cat's bed. My cat is the only girl allowed to sleep with me." She laughed and said, "Oh you guys are so much fun, I havent had this much fun in months". I then solidified the 'friday date', and she said, "Well I am definitely coming on Friday, no matter what. And if I said no, I am full of shit so you better make me go."

When we reach her vehicle, I give her a quick hug and she leaves. I text her 15 minutes later with, "Too bad you are so clingy, we could never date because you're already trying to move in with me!". She responds with: "Haha I wasn't serious". I text her 'goodnight', and that's the end. My plan is to not initiate any contact with her until Friday. I don't really know how to escalate the situation, but im hoping Friday will be an opportunity to transform this long term 'just friends' relationship into something more. Any tips appreciated!
