Flirting

Is this girl flirting with me?

We were at a party and she started complaining to me with her friend about how they were lonely, i think of my self as unattractive and fat (insecure) and thought she wanted me to set her up with someone, i tried and it failed but the rest of the night she kept complaining to me about different things, like how about her legs hurt and when i told her you can't sit anywhere she told me to pick her up, which i stupidly shrugged off. We have kept contact messaging every couple of hours and i personally dont think that i am attractive enough to get her, she is a model in my town and many people including myself think that she is very attracting. Should i try and make a move and if i do how should i do it?
