From all your posting on your ex, I think u should not "give"
her the $$. Have had a previous experience once, similar to yours.
Ended up got borrow no return.
Next, even IF you still likes her, your should not lend her the $$
oso. Although you did not mentioned anything about who initiated
the broke up (when she was with you). Her latest ex may have broke
up with her due to the $$ issue, which you said that you have lend
here a few $K already.
Bro, think again...
As what firelce mentioned, if you really wanna help, get her to
some family ctr or help group. By lending her $$ is not helping
her.
