How can I know that this boy likes me?

the boy I'm talking about is in school he always ask for money in recess or lunch but when I started transfer in that school then I saw him, I fall-in love with him then when my clmates know that I am rich then he start asking money from me .sigh... its obvious that I'll give him some money because I really like him. For the past few months now we are becoming close well I guess because I'll always give him money whenever he asks but sometimes I always thinks that he likes me. What should I do now? how should do I know that this boy likes me or not?
