Perhaps you should get married immediately and be in charge of his finance !

just kidding but sure is a good idea, agree?
Frankly speaking, it is no point persuading yr BF as he is one who treasure kinship aka same like me
and I can tell you, it is very difficult to reject, let alone lecturing.
My suggestion to you (for you, to yr BF) is to try and minimise the amount. If somemore wants to borrow eg $500, just tell them don't have so much as you plan to buy a new PC or whatever, chnaces are they will always accept whatever amount so long as you give. so, just donate $1-200 lor
That is how I manged after "donating" many thousands
