I need my future...

I'm 15 and I started dating this guy after a really rough patch of depression and suicidal thoughts. He's my everything. He picked me up. I've been clean of self harm for a year because he keeps me on my feet. And we're so close. It's almost been a year and I want my life to start so bad...I want to be his. I want to start a life with him and be a wife and a mother and have an accomplished career. And I just don't know how to make it stop hurting that I'm not living my future...he makes me happy and distracts me but there's just some days where I can't forget that I'm not living my own life...
