My boyfriend

My boyfriend has told me slot that he wants to marry me and I want to marry him someday. We were going to get married around the time I turn 18 but I told him I wanted to wait a year because I will be a freshman in college and it would be very stressful for me. The thing is though is that I won't have sex till marriage and I feel kinda bad because I am making him wait awhile because he is older than me I know it's my choice when I have sex and he doesn't ever try to ask or pressure me into having sex I just still feel bad about it.
