He's saying there are alot of things about you that he doesn't like! Like for example, if someone is against biting nails and his girlfriend does it then that may be a flaw that he has against her!
It means you have a lot of history
It means he likes you - a lot.
When a guy says you are a hand full it could be meant in a good way. He may mean that you are bold in what you want, or that you are a lot of fun.
I think it means he really, really loves her a lot.
Probably means that you mean a lot, A LOT to him. If he says that, you are mostly 90% or even 99% of his life. lol. ;) He means he's worried to lose you, and he wants you to convince him your his forever. ;D
plain n simple...you have the whole package...beauty, brains, body
It means that he likes you a lot and would probably date you if he did not have a girlfriend.
it means he wants you there for a little bit but then leave
It could mean a lot of things but I think it means he loves being inside your heart.
it means that he likes you too, he notices you a lot.
If a guy says he likes you a lot it is likely that he likes you a lot. If his actions match, for example he treats you well, you can bet that he likes you. Be careful if he doesn't treat you well, he might be lying to you in hopes that you will flirt with him.
If he's being that straightforward, he probably means exactly what he says: He likes you a lot!
