Girls, please help me. I have this friend who i like but is confusing me....What does she mean?

So i texted this girl who is the arch-nemesis of my best friend who is a girl. So we started talking and have been constantly for 2 weeks. Well i am getting this huge crush on her and she has been saying something that are very confusing. So first of she has never met me in person b/c of my best friend. So a couple of days ago she told me that she thinks that she is in love with me. Then a few days before that she had asked if i would have sex with her; like if it just happened would I. (BTW. we have sent pics of what we look like to each other). We have been flirting A LOT and i am wanting to ask her out, but only when we meet in person, but she is confusing me with the sex question and the I love you. Does she really mean it and what is with the sex question. Thanks in advance.
