Help I'm stuck

My bf and I have been dating 3 years. We are somewhat long distance case for college by see each other monthly. I do him last week but am so unhappy rn. I'm 22 and in college and he works. In the 3 years we've been dating he has planned nothing with me. I have taken him to concerts, day trips and all. He has done nothing like this for me. Financially he can easily take me away for a few nights yet never has even suggested that. I always bring this up and he never changes. I know that he loves me but he never wants to make memories with me. I am 22 and applying to medical school this summer and transferring schools I'm beyond stressed and you think he would want to help me and destress me... nope. I'm ready to just say let's be friends because all this is too much for me. He needs to get his life together and so do I. We did a break right when we started dating due to craziness in both our lives and ended up better. It's just that I'm 22 and it's summer and want to do fun things with my bf. I'm in crazy to think he would have changed this year. He has this huge promise that before I start medical school he will take me on a cruise. I honestly have no faith in him since he promised to take me out for a belated birthday dinner and did nothing for me. What the hell do I do? He's a nice guy and all but I can't keep waiting on him to be what I want. It doesn't have to be expensive trips just anything to show he wants to be with me
