Is it worth it getting back with my ex if hes missing his ex and telling me he wants to work on himself for a good while

Idk yall call me a bird but i miss this man, we broke up 8 months ago after dating for 3 months and i felt the most connected w him than w anyone else ive been with. Im 22 but Im just scared I wont find love any time soon cause I had plans of settling down young, at least my family is so used to that but since im gay its just different but I yearn to have a similar path and be a father someday. I want to wait for him and get fit again cause i kind of let myself go since he left and he acknowledged it when we reconciled a month ago and he said he wanted space.

Typing this out is making me realize he has a different perspective and wants something else obviously im just so afraid of growing old and being alone.

Any older gays that can give me their perspective on life?
