I'm also 13,I really love him,the problem is that many girls in da class love him,one of his freindz told me that he loves me but I'm not sure if he really loves me,maybe he don't if I tell him and he says no, I'll be among those girls he already said no and I don't want to,every one says that we'll form a good couple,what do I have to do?

Befriend him and get to know him better for a couple of years. Then it would be the time to talk about love.

Give it time , show him the side of you that is special and that stands out from the crowd, let him come to you because then you will DEFIANTLY know if he likes you and then smooth sailing from there

Just be his firend and help him out if you can and see where thinks go from they

Be optimistic :) show him your happy side and always smile. Guys love happy girls.
