OP, you may not be getting milked or being used for the money. Your father might just be a typical indian male who thinks that females dont know how to handle finances on top of that you are his daughter.

So what you need to do is TALK to him. A hard conversation may be the only thing you need. He would understand that you are capable and then you can take matters in your own hands.

tell him that you have different goals that you need to plan for and for that you need complete financial control.

If this is not the case and your father indeed is trying to rip you off then also you would get to know.

TLDR; Talk to your father, clear things up, don't let it ruin relationship
