Money or emotions in a relationship?

I have been in relationship with this girl for last 1 year now, she has been great - have her own little issues but more or less the ride had been good enough. Now occasionally she ask me for some money for various things like her rent , mobile recharge n all - and this spend grew upto 20k.

Now I am an sole bread winner of my family and everytime she ask for money she gives some reason that she is short of money and how she Is going to repay after her salary is credited and all - but so far got nothing. Yesterday I was pissed off when she asked to pay her new flat deposit and said will pay on the 1st week. And said very clearly about the money I owe her

My issue with this situation is not that she is asking for money but rather she doesn't seem to bother to repay - and if she doesn't want to repay - then don't say the plans to do so.

Now she is saying I want a break up and doesn't want to continue this relationship

What should I do? Ps - she is having genuine good salary with some medical expenses of her dad
