<human>: Summarize the given text in a few sentences.

We have been together for a year, halfway-through which I graduated from college and got my first-ever job, making 68K. I had to move 150 miles away, though we see each other every weekend. He used to make 80K before deciding to go back to school, and he currently makes about 15-20K, by being a TA and doing some side projects. He will be in school for another two years.

We got a credit card together a few months ago under the same account, to use things we did together like trips and dates, so we would not have to fight over who pays this time. Since I have a job and he does not, we agreed to pay it off 75/25.

Lately I've been finding out that he is using this card to pay for things like gas, clothes, groceries, alcohol, going out to restaurants, and to pay his Internet and cable bills, totaling $500 so far this month. I am very upset by this and have brought it up several times, but he continues to do this. I feel bad because some of that can be excused as necessities, and it seems only fair because I have an income and he does not. But it's not like we're even married or engaged... So if he can't afford to go out to eat at a restaurant, he shouldn't, and that's HIS problem, not mine.

I also have to worry about paying off my college loans, paying off my car, and paying off this ever-growing credit card debt. He only has to make car payments, since his parents bought him a house so rent and utilities are taken care of.

I can't decide whether or not I have a right to feel upset by this, or how serious of an issue it is.
<bot>: My boyfriend makes about 1/4 the money I do, and uses a credit card that I pay 3/4 for, for everything. Do I have a right to be upset?
