It can mean various things. All good things, and you should be pleased with this phrase, in other words he loves you. It's an old term which basically means you're his/her only love, nobody else. However it can also be related with just a pet name such as 'babe' or 'baby' they're more thrown around rather than what 'my love' is though. It's a good thing, all in all he really really likes you.
It is a token of friendship. Obviously it can mean a range of things depending on whether he uses it for everybody or just you. Most likely, it hints to a crush or attempted flirting. But I wouldn't make anything too serious out of it just yet.
It means that they like you and think you like them!!!lol
that means he loves u
it probably means he loves you?
If you have to ask then no he doesn't.
they lke or love u
It means that he has a lot of affection for you and that you are special to him.
he is playing gard to get and he must not love you.
It could mean either he's in love with her or he wants to sleep with her or its just a friendly I love you.
It could mean that he loves you, but it is more likely that he just wants to have sex with you.
a sign of loyalty.
That there is another woman on the side
you either over did something or you just surprised him.
He doesn't want to get married yet I guess
"You mean a lot to me" is not the same as "I love you." He might love you or he might just consider you a very good friend. You'll have to ask to be sure.
It can mean anything between he's in love with you to he wants to sleep with you.
