is it worth upgrading a quite short 7/10 gf who really really loves you, to date a taller 8.5/10 girl who has a "crush" on you but you don't really know her very well.
Don't know if it's worth it, she's definitely cuter and has a better body, but also having a better looking gf might be a bigger risk because I find they tend to be more narcissistic and materialistic.
