Some backstory first: I started messaging this girl the other day. At first I was being funny/mysterious/flirty. I never met her irl. She only knows who I am through Facebook but I only started messaging her a day ago so this is the 2nd day we've been talking. I was surprised for how long she can keep a conversation going. We can talk for hours so she definately likes me. Today however, I felt she was a bit too personal and emotional from what she was texting me.

Today the conversation went in a way where she told me she takes birth control then went to when she lost her virginity, to what her friends think about her, she told me that she is anxious and insecure about herself and then went on about how she was severely stressed out for this presentation she wasnt ready for and even said that she was crying because she was so stressed. The whole time I was trying to comfort her. It wasn't really appropriate to flirt and make jokes anymore so I kinda had to be serious the whole time. This is the first girl I messaged that's told me so much about her in only the second day I messaged her. Is she just using me as a shoulder to lean on now am I in the friendzone? Do all girls behave this way for men they might be interested in? Im very confused.
