she freaking left? you're goddamned gold, dude. the awkward 'do I sleep over, do I leave' is solved--****ing marry this one, mang. she has three things going for her:
1) she gives a mean blowjob (though that will disappear after matrimony)
2) she can stomach you enough to sleep with you
3) she's basically a dude: leaving under suspicious circumstances? she likely has klinefelter's syndrome (look it up: she has a y chromosome)
