Niffler

There used to be one of these on here, I remember, but I just searched everywhere and couldn't seem to find it.
Anyway, this is the place where we can all come for other people's input on situation; in other words... ADVICE!

OK, so as for me, I just confused about something. A few weeks ago I met a girl that works in a club I go to and I am really into her. She seemed interested and we flirted for a couple visits to her work, but she'd never call me outside of work or return my calls and I think she even gave me her sisters number or something.
So last night I went there to see her and she wasn't there, but I met this other girl who was really nice and extremely friendly (touchy-feely). She was pretty but I didn't like her emotionally as much as the first girl. Anyway, we ended up making out pretty hardcore.
This morning the first girl called me twice while I was sleeping, and I missed the calls. I called her back and she didn't answer. Now here are the questions:
1. Do you think she heard about what happened last night?, cuz she had never called me before.
2. Did I do anything wrong? Girl #1 showed interest, but only sometimes and I am single, right?
3. Then why do I feel so bad that she might have found out?
4. What do I do now? I still like girl #1 (she's so shy), but I am attracted to girl #2 because she's a lot more outgoing and wants to hang out. I am not good at being the agressor, I like that girl #2 comes after me, but I am more interested in girl #1. Should I just forget about both of them?

AAAHHH!!! I am so confused. I appreciate any help. Thanks.
