Why did she do that? It's definitive right?

(Hey, it's not that long. Don't skip this question. Trust me, the story is very immersive and interesting. I can clearly become an author if I want to lol so read on and help me out guys and girls )))

Okay this girl I've been dating. On our first date she told me she has a bf who lives in ANOTHER COUNTRY, who she doesn't want to talk about.

She gives me her email address, phone number, shows me her place where she lives, etc. Gives me her photos, she has my photos, she's VERY comfortable with me, loves to make excuses to touch or grab me, tells me her personal personal problems, etc.

On our 2nd date, she changed her Facebook RelationShip Status to "SINGLE".

Here's the interesting part: her only two friends on her facebook profile is ME and her dad. That's it. So that means she's giving me a hint right?

3 more dates pass by. She becomes way too comfortable with me. We hug, kiss on the cheeks, etc, all is in the house.

That "supposed bf who lives in her homecountry" still swims around in my head.

She goes to homecountry for summer vacation, and then changes her Facebook status to :"IT'S COMPLICATED".

On top of that, she starts sending me messages typed in 'pink and red' color.

Why does she do all that?

-She already knows I like her. I told her already.

-I've started ending messages by saying 'I love U', she sends me back smiley faces.

-She comes back in a week. Should I drop a kiss on her lips? And I'm definitely proposing for a more serious relationship btw(so throw some tops here too, I've had girlfriend's in the past, but I always liked them, this girl, I LOVE her, something about her, her personality, different from any girl I ever met).

Overview:

-Gave me email address/phone number first day we met on the street. (And it was the real stuff too, not made up to get me away)

-First date movies. She sat TOO CLOSE to me. Our faces were 2 inches apart, and she did this for all our movie-dates.

-Tells me everything. Personal problems at home too(lives with mom)

-She's 18. I'm 18.

-2 dramatic jumps from "In a relationship" to "SINGLE" to "IT'S COMPLICATED". Is it complicated because I tell her I love her but haven't asked her out? She made it "IT's COMPLICATED" only after I told her I love her.

-Either the "homecountry" bf never existed, or he's "bye bye" now.
