when I was twenty there's no way I'd date a man in his thirties--yuck! old men!

I'd say if we were talking she was 30 and you were 45, that would be one thing but she's really still a child. she has a lot of growing to do and unless you're emotionally stunted, then I'd try and find someone more your own age. sorry if this comes off harsh, but it's just my two cents and feel free to ignore if you wish.
