Search Results: talking to him outside of class

This girl I am very interested in that I met in class is confusing the fuck out of me. We started off just talking in class and then one day after class we talked in the library for an hour and a half or so. Since then she has initiated conversations less and less. So I thought maybe she wasn't interested and just wanted me to quit pursuing her so the last few days I made no attempt to talk to her then on the way out of class today she waited outside of class I thought for the other people in our friends group and I just walked straight out thinking she was not waiting for me. She left the other people without saying a word going the same direction I was but she didn't say anything and I basically just walked faster cause I did not know what to say and I thought she wasn't interested.

So I'm going into my Senior year of High School. I really like two sophomore girls. Over the last year, both showed some signs they like me. I haven't really seen either of them over the summer, but I'd like to continue talking and flirting when school starts again. To make this easier, I'll just list when happened under Girl A and Girl B.

GIRL A
I asked her out. She said she has a boyfriend. (First time we talked) - not a smart move by me -
she was talking to some other guys but no official boyfriend

After I asked her, she stared at me every day
Quickly meet my eyes in the halls or hold for 1-3 seconds
Play with her hair while she looked
This would literally happen 3-5 times a day
always faced my direction
walked near / with me in the hallways

After being rejected, I was embarrassed and didn't talk to her outside of eye contact and stupid stuff. Over summer, I messaged her insta. I said :
Hey. Could we talk?

she didn't respond but she hasn't actually seen it yet (ik she could have just not opened the message)

GIRL B :
- She would say Hi to me every day (we had one class together, but also saw each other in free sometimes)
- She would always initiate conversations with me
- She insisted on taking pictures with me
- She stole my phone and took stupid pictures with a friend (also a girl)
- I would see her looking at me in the hallways every few days
- She said she would have went to junior prom with me (I went with a girl my friend set me up with, but we didn't really connect well)
- She (jokingly) said we are practically dating
- She followed all my social media
- She complimented me on my shirt, said (blank) is really my color, etc.
- She smiled a lot and laughed at dumb jokes I made

I realize the difference in these two are different. One girl sought me out to talk and the other stared a lot. The thing is, I have feelings for both of them, so any insight as to what each girl is thinking as well as what I should do is much appreciated.
