Halalkan dia / made she mine

I need some funding to help me to make she mine. She is crazy enough to wait for me until I complete my bachelor degree. I just wish that she can be mine. I dont want to lose her. She is my everything. I promised her that I will bring at least a ring to marry her. She is the most amazing woman. She understand my situation and didnt asked me to buy the ring that I showed her, instead she demand nothing. I want to at least give her decent wedding ring for all the hard the she willing to go through with me. To be honest, I have manage to collect the enough money to buy her a decent ring. Through this, I only want to try if i could give her a better ring. Maybe a carrat diamond. I know she will be mad if she know this. But I am a man that want to give the best that the love of my life deserved. Thanks.
