Marriage

So I know a lot of people are gonna say “you shouldn’t even be worried about that you’re so young you have a whole life ahead of you” I know that this is just a vent. So I’m 17 I graduate this school year & go to college right after. I plan on starting a business & becoming a psychologist for war veterans, children & teenagers, & people who deal with trauma. My boyfriend & I were talking and he said if we were to get married he wants me to have his last name & only his last name. I said well no I’d want it to be hyphened because I want his last name but I also want to keep my last name because I’m building a name for myself. He said I’m proud of you for that but we wouldn’t get married then because it’s my name or nothing at all. Now that hurt a lot because I know shit happens and life changes unexpectedly & I didn’t count of it for sure but we planned for a life with each other if we were to stay together and I was definitely looking forward to a life with him if nothing changed. We are going to the same college together, different majors because he’s taking over his fathers business but everything else we expected to be together. Him saying he wouldn’t marry be because I wanna keep my last name hurt but I know I have to respect how he feels but love myself enough to let go. I wanna build a life with him & get married and I know I’m young opinions can change but I don’t know if I wanna stay with him still knowing we probably won’t have a future together simply because he wouldn’t marry me if I didn’t take only his last name. I don’t know if I want to waste all this time & get my heart broken in the end vs just letting go now & save myself now. And I know I’m young so I should just wait & see because as time changes feelings change too so why end something so great when I don’t know if that’s the outcome for sure.
