<human>: Can you succinctly summarize the text in 1-3 sentences?

Hi everybody,

This girl (22 y/o) has been out of her recent relationship with her ex for a month now.  She's in my class and I really do think she likes me, but I'm not sure.  That's why I would love to hear your opinion.  Last week, she asked me if I wanted to grab lunch (I paid for the both of us) with her and I said yes.  During lunch, she told me we should come back here and grab food again and possibly study together.  Obviously, I said yes and we exchanged numbers.  Now, she would randomly text me.  Yesterday, we grabbed dinner (nothing fancy) and she told me she would pay for the both of us.  We have been studying together lately (just the two of us); the last time was on Monday.  When we were about to head home, she asked if I was available any other times so we can get together again to study.  We are meeting up this week and during the weekend.  Today, we were sitting next to each other in class and one of her very good friends comes in and sits a couple rows in front of us.  I tell her "hey, your friend is right there".  She tells me "oh, I didn't see him".  I was expecting something along the lines of her asking him to sit with us, because the three of us would are friends.  I'm also curious as to why she doesn't ask her friend to join us in our study sessions.  What's a bit strange is she's usually on her phone texting her friend, possibly a guy, when we are together.  I really want to make a move, but am hesitant with how she has been acting.
