<human>: Give me a shortened version of the text

So I (M21) am interested in this girl (20) at my school. We met a couple of weeks ago and have been hanging out very steadily since. We get along really well and it seems that we both enjoy being around each other. 

She has been physical with me, in the sense that I'll make a joke and she will hit my arm. I know that that can be considered flirting but she has said that she is like that with all her friends(I'm a little skeptical).

So it seems like she is giving me signs that she is interested in me but what she has told me about herself makes me think twice. I'm just not sure if I'm seeing things quite clearly.
<bot>: This girl seems interested in me but I'm double guessing myself because of conversations we've had and who she seems to be.
