I can't stand my best friend anymore

It began when i lent him money (about 500$). He said he really needs it for his car so i gave it to him. Shortly after that we went to a festival (made the plans about a year before) after we arrived he told me he has no money and i have to pay for erverything (another 250$). When I started college I had to pay for a lot of things, I asked him if he could start paying me back but he said he is still low on money and is not able to give any of it back. I had to ask my parents for money (i felt really bad because we dont have much money ourselves).

Later i found out that he used this money to buy weed and go on holidays with friends i didnt even know he had. At some point he gave me the money back but I'm still really mad about this. I think he just took advantage of me?

There are a lot of other things but this definitely bothers me the most.
