How Do You Handle a Difficult Cousin?

Hey everyone, I’ve been struggling with my relationship with my cousin lately and could really use some advice. We’ve always been close, but lately, they’ve been acting super entitled, constantly asking for favors, never returning the same energy, and even borrowing money without any plan to pay it back. It’s starting to put a strain on our relationship, but I don’t want to create unnecessary drama in the family. How do you handle situations like this?
