A few weeks ago, I wrote a thread about a big self-improvement project I would take on when it comes to women and dating. I received a lot of really good advice and so far this semester (although limited opportunities so far) it seems to be on the right track.
I did mention that I would give it a go with a girl I was interested in before break - I wasn't going clean slate. I gave her a call...nothing (it was later that night after I had a real busy day so I figured that might explain this one). I call a couple days later around mid-day...nothing, BUT she calls back about two hours later when I was at the gym, so things are back on. I call her a little after I get back from the gym and she picks up.
After the hi, what's up, how's the start of your semester going stage, I get down to business. I give her the time and place I had in mind for a chance to get some coffee and thus, "catch up since break

" Now here comes the ambiguity...
she seemed into the idea and was very upbeat about it, but she is pretty sure she has class around that time (fine) and she'll call me early this week to let me know when she is free (we haven't been back at school a full week yet so no one is 100% sure of their schedule, but this is an iffy part for me). I thought that was that and was ready to move on with my day...but she kept me on the line, asking about a small, major-based hands-on class I took last year because she was taking it this semester (basically what I thought of the class, how I did in the class, what I liked/didn't like from the class, etc). I threw in a story or two, popped a little C+F, we connected on a few things, and she seemed genuine as usual. So she seemed to take an interest in me in connection to the class, and at the end of the call once again mentioned she will let me know what time this week works best.
Here are my questions to you guys:
1.) My plan right now is to call/text her on Wednesday afternoon if I don't hear anything. I really don't like letting things go or letting them go stale...taking action is the one way I will know what's going on. Is this the best thing to do?
2.) A friend of mine thinks the fact she kept me on to ask me things in regard to myself with that class was a good thing, since she simply could have not called back to begin with or could have just waited until the class began to know what's going on. I tend to think she just wanted to make conversation to be nice. Your thoughts?
3.) As you can tell, I am a bit pessimistic when it comes to ambiguity and women. If I don't hear an outright yes with the date and time locked in right away, I assume it's a no. I've been flaked on/stood up before by women (recently), causing this slight paranoia. I know I didn't offer a lot of "clues," but am I staring into another unwinnable situation?
