So, I opened up the first 2 face shots and was like "uhhh, no".  Then I opened up the third pic of the body in bra in panties and was like "woah, what the hell?!", had to recheck other two pics again to make sure it was the same girl.  I have to assume for rating purposes that the body is maintained like that and it wasn't just a good snapshot in time.
Now this is all science GB, so reporting it like it is...
- Face (and knowing she's 6'1") =  4.5
5: Starting to be unattractive, but certain qualities work in her favor. Nothing major, but minor problems are more common
			4: Not attractive. Major flaws start piling up (overweight, blemishes, etc.)
- Body = 7.5
8: One of the hotter women at the club, one of the hotter girls at school (upper class of hot women)
			7: Cute girl at the club, in classes, at work, in apt building. Definitely cute, but not tops locally. 
OVERALL: Above averages out to an offdee official 6 which I think is very appropriate, and she falls in line exactly with that rating's definition.
6: Fairly attractive, no major flaws but maybe minor ones

With all that said you are definitely overthinking this.  You are in a slump and you have a great body being offered up on a platter.  Move forward and use it to build up your confidence.  Be very up front with her that you're just enjoying dating right now and not looking for anything serious...it will actually make her want you more.  Rome wasn't built in a day GB, start small and dream big! Have fun!
