Search Results: limited time together

There is this girl I met a few years ago, and we dated. Nothing happened at that time, as I was just out of a long relationship, and after a big argument, we stopped talking for two years. She appeared out of the blue one and a half month ago, asking me out. We went out, and since then, excepting a few days, she contacts me every day, asking me to meet. She even kept daily contact when I left the country for one month.

Lately, it happened for her to call me and ask if I want to spend time with her multiple times a day, after we have already seen each other in the same day. Also, it happened a few times to tell her that I can't meet her on that day, and that we'll go out the next day, and she made sure to call next day early in the morning to make sure I can make plans with her.

I can't really say we get intimate, we make a lot of body contact, and she usually sits really close to me, sometimes leaning on me, but that is about all. When we rarely go out with other people, she almost always makes lots of body contact with me. She sometimes seems to get jealous, acting totally different and rude when I deal with other women.

I don't understand what is happening, it doesn't look like things are advancing, even if I try to. I also considered being in the friendzone, but from my experience, friendzoned people aren't contacted daily, even multiple times a day. Her wanting to spend more and more time with me, wanting to meet multiple times a day, also rises a question mark. Jealousy also makes things more strange.
People seeing us together and the way we act are sure we are in a relationship.

The only thing that sounded like a rejection is that she told me she is lately interested in older guys, like 30yo, she being 20. I am 21, and a bit in love with her.

It is hard to explain everything in such a limited space, but I hope you guys can understand what I mean. Please tell me what you think, and give me some advice.
