If god can give me someone to teach me a lesson,then why can he send me a good guy.?

i told my mother i would never end up with a ignorant person and this guy came along started to like me but in the end it was a lesson learned because he was a hoe and almost every one at my school started to not like me even the ones that didn't know me. if god can send someone to teach me a lesson then wheres my hero or was my future love that guy because sometime i run into him out of school and the past guys that i liked in the past, i've never seen out side before its like from time to time i run in to him.
