10 years apart❤

So I'm 19 and my boyfriend is 29, almost 30. We don't get judged for it, both of our families are supportive, but I still have some hesitations. Like what if by the time I'm ready to have kids, he's not because he's "too old?" What if he leaves me one day because I'm at a different point in my life than he is? Like he's already been to college and has a good job. I have only graduated high school and am currently working as a babysitter. Maybe I'm overthinking? I don't know. Has anyone else experienced these fears? How did you overcome them?
