I remember your case, you are very busy in your family business. Sorry I cannot type Chinese today.
This girl wants a marriage and she is too selfish for you. (Can she sell fish?? Ha Ha) She is not your wife and should at least pay her share of expenses when going out. She wants your money, time and wants a family which you are not ready.
I always want to pay for my girl friend. A good girlfriend would offer to pay her share, or if you are paying, not to cost you too much money.
"fly" her. Work hard in your business and try later. There are lots of fat girls around if you like fat girls.
Just let her walk. She brings nothing to the relationship.
If she wants to be bought, then let some rich dude pay for her and anything that is based on money isn't going to last. The rich dude would find someone prettier and move on.
