If it's just an ordinary colleague relationship, what is the reason to borrow money?
And your girlfriend seems to be very nice and cares about you! Did you ask her why? If that person has helped your girlfriend a lot, you should help him anyway.
If she has no justifiable reason, you can explain your present situation to her!
I think you should still have some savings now, that's why she said so! If she is a person worth living with, then she deserves to be treated like this! Don't you think you should think about your future?
This problem is something you should consider. You need to think about what you can do now, what you can bring to your family/parents, what kind of life you want and what kind of efforts you will make!
In fact, if you are decisive, you will find that this problem is actually a small case for you!
Come on! Life needs encouragement and understanding! ! !
