Wow dude, you are defiantly putting too much energy in to this girl! Chill for a bit,
listen to what the guys are saying, you need to cool off! Stop putting that ***** on the pedestal!
I get what your saying that you have no other options right now but SHE doesn’t know that, the less she knows the better which is why you should keep your messages short and sweet as it keeps you a mystery (which is attractive)
Just because she’s having to cancel on dates does not mean she’s not interested, she might have very good reasons which may have nothing to do with you at all! If I was Ill and had to cancel on a girl (which I have) and she accused me of playing games/being flaky (which happened) I’d tell her to “do one” (which I did) lol so stop being selfish, it’s not all about you! lol
the fact she is offering other dates is a GOOD THING so don’t worry! What’s the urgency? what’s wrong with next week? You sound like the kind of guy who is always overanalysing situations, I know its hard to switch off sometimes but a trick I find is to recognise when your thinking about something and actively change your thoughts by doing something active, watch a film, read a book, meet up with a friend, do anything that keeps your mind off whatever is troubling you then you can look at it again from a fresh perspective!
Good luck
