I'm always imagining my future with my crush

I've liked this guy for about 6 months, and I can't stop thinking about him. I think he knows that I like him but he doesn't seem care. There was a time when I asked him to pick me up and drive me home, he did. Sometimes he did what I told him to do but he never shows any interest in me. I feel like being friend zoned but I want him so bad to be my future partner in life. I have imagined a good life with him, having beautiful house, kids, nice life and everything. It's been on my mind all the time and before I go to bed I wish I would have a dream about him. I love him but I don't think he has the same feelings for me. I don't want to move on, I really want him!! And also the problem is I'm 23 and he is 19 ._.
