I need relationship help

Marlee

I've been chasing this guy for 8 months and I see him almost every day and I like him alot and he keeps showing me signs that he likes me and he keeps saying he doesnt like me. I asked if it was becuase I am 6 feet tall and you are 6 foot 2 and he said no. Idk. Does anyone have any idea what the problem could be or how to get him to like me back?
