<human>: Can you condense the text into three sentences or less?

So I (F-25) had a late start in college and I'm just now starting my senior year.  About 8 months ago I divorced my husband (M-27) and naturally that was a huge life change. However, things have been ok for the most part lately. I started dating and didn't really care for it. Naturally I met someone when I wasn't looking lol
This man is barely a man.  My SO is 19M and has three years of school left. But this doesn't stop me and we fell in love(I'm quick to love). While the relationship is young, we have spent countless hours talking and playing out hypothetical life situations and we have only grown closer.  
Then this current semester started and everything hit me. We have very different upbringing and that's not a bad things but he doesn't work while in school and I'm not sure he's to serious about school itself.  And of course, I graduate in a year.  What happens then?  I can't shake the thought that I'm his stepping stone into serious relationships like my ex husband was for me. He's 19. I would love nothing more than to settle down but I think that's too much to ask from him.  I just wish I knew how to handle this.  Suddenly all I can think about is "I have to break up with you in a year" it's a dark cloud lingering and I hate it because I just want to be able to enjoy this last year with him. 
Thoughts?
<bot>: dating again and I picked a 19 year old.  I graduate in a year and he doesn't. I just want to enjoy the time i have left with him but I can't stop thinking about graduation.
