Does anyone else have a girlfriend that only thinks of herself?

i have this girlfreind who always eats everything and srinks everything and does things only for herself, like whens he goes grocery shopping she will only buy things she likes to eat, when she asks what i want i tell her and she doesnt get the things anyways, like snacks and stuff if i wait like 2 days not joking she will have it gone, like a whole box of cereal will be gone in 2 days, she eats it in the morning and before she goes to bed, then tonight i bought 100 dollar wine to just relax with, well im not into drinking but i thought i would like it since it was cyder flavored, well i opened it and went to the bathroom so she went in the kitchen and had a glass of it already and then i had to rush over to my parents for 15 minutes, i come home and its gone, she said " what you dont drink".... so then earlier today she went coat shopping for herself she spent 80 dollars on a coat, and she brought my daughter in with her and my daughter was still wearing her spring jacket its 17 degreese here, i was mad i asked i gave you money thinking you would atleast get our daughter a coat, her excuse was i didnt have enough money... i dont get it do you have this problem??? and always always always always she knows everything and she is allways the victim....
