Why is my friend acting this way?

Ryan Markson Asked: Why is my friend acting this way?

Ok so my best friend Rachel (were 16) got molested by her boyfriend Greg. (also 16) He got her naked and was feeling her up and kissing her neck against her will, and she kept trying to push him off and stuff. But then he let go of her and ran out of the room and out her house cause he heard a car pull up, thinking it was her parents. (Who are away on business)

Actually, it was me. I didnt get why he was running out, but I went inside to see Rachel, and came into her room, she saw me, and run toward me. She jumped into my arms, crying and hugging me tightly.
Then we sat on the bed, and I comforted her and held her close as she told me the story. Only thing is, she was naked, and we were hugging close. When we finally addressed this, after like 10 minutes, she blushed a lot and went to get clothes.
After that, we hung at her house talking, and she had my hand, and was hugging it to her chest, the whole time. (And Rachels got really huge boobs, so I had my hand like cupped on one of them for that whole time)

She gave me these glowing, adoring smiles all day. She hugged me a lot, and the hugs were much tighter and closer and longer than normal. While talking to me shed lie down on the couch and do a sexy pose.

Weve been best friends for 5 years, were incredibly close and have no secrets. Ive always known her bra size, (32 E) that she gets waxes down there and known all the things that secretly turn her on, etc. Shes always known all my secrets; like she knows Im sterile (cant have kids)

But today was justodd. I know, I saw her naked (and snuggled with her nude body) But its like shes comfortable with on me on a new level now.
Oh yeah and she was flirting with me. Did all the stuff, like twirling her hair, leaning in, kissing my cheek, etc. She also kept playing with her boobs, like she wanted me to watch.
Sure, weve playfully flirted before, but its never this sexual or specific, and given what had just happened, it seemed out of place.
Whats up? Whats happening? Why is she acting like this? It almost seems like she likes me now, or at least wants to hook up. Does she? The idea of us dating, or hooking up has never even occurred to me, , but I dunno.
