Bf ask me for money Always !

So I’m pretty giving or what not but my boyfriend ask me for money back to back even though it’s like $5-$10 he always ask can he borrow money and it’s honestly annoying because when he does get money he just sends me $50 and thinks it’s ok but sends his mom almost $200 and it honestly makes me mad because she doesn’t give. Him money every but he always gives her more than me when I’m the only one helping him out
