Search Results: stay up and chat with a girl

A friend of my best friend and I have recently started getting closer this past week, but I'm unsure whether to take all these flirting signals serious or not. I'll give you a gist of everything

Positives:
1. We make a lot of physical contact.
- In any situation, you'd find (person of interest) touching me in some way or form. Whether it's hugging, touching my face, putting his arm around me, or even just a simple hand on my thigh. Nothing sexual though.

2. We've been cuddling. A lot.
- A couple of us drank at (person of interest)'s house last week, and throughout the whole night, we were either leaning on each other or he had his arm around me. When it came to our sleeping arrangements, he and I shared a couch and spooned.
- A few nights after that, we all stayed at his place after going to the bars, and the same sleeping arrangement happened. Throughout the whole night we hugged each other.

3. I always catch him staring at me.
- In any situation, I normally find his eyes on me. If we're sitting together, he and I will catch eye contact with each other. I usually break the stare, because I'm an awkward person, but he normally smiles.

4. He teases me quite a lot.
- He find any reason to poke fun at me or cause some type of debate. All in fun, of course.

5. Our friends have also noticed us becoming closer, and constantly tease us about "how cute we are" and we don't fight or deny anything that they say.
- They'll send us both snapchats of us sitting together and whatnot, with drawn hearts and "cute couple" captions.

6. Even though we're around other girls who (I believe) are more attractive, he'll still stick around me.

Negatives:
7. He will talk about other girls in front of me.
- I hang more around guys, so while they're all having "guy talk" and I'm around, he has no problem chatting it up about girls he finds hot.

Help me figure this out, because I'm most definitely confused.
