Expensive gifts from the boyfriend. How should I react?

My boyfriend (27 years) and me (19) have been dating for about 4 months. We really love each other and planning to live together in the near future:) The problem is that he has always been giving me not only lot of small but cute presents but also REALLY Expensive ones.

I just don't know what to do.. I mean I can't afford to do the same toward him( I am just a student) whereas he has already finished Medical School and working) Please don't think that he is trying to "buy" me with all that presents-it's not true) He told me that he feels so happy to make ME happy!:) hah And yea) he is not bad looking or something))) I am telling that because someone might say that he is trying to buy my beauty)- it's not true!) so what should I do?))) Please help!
