Is my boyfriend taking advantage of me?

My boyfriend.
we went out together and we were ordered a food at
Restaurants but he doesn't pay for his meals he always tell me that he doesn't have money even i said you pay for your meals i do the same he was upset and i pay anyway ;( . Even when I went out with him with his friend when bill came he gave me the bill to pay for because they stare at me and he told me when my salary came i will give u back then he doesn't he lied. I don't know why he do that if he pay for himself its better. I avoid to go out with his friends they are group so he will do the same to let me pay for. I am thinking to end my relationship with him am i doing right or bad?
