Recently broke up with my first boyfriend

So I recently broke up with my first ever boyfriend because I felt like we didn't have much in common and it felt like the right thing to do at the time but he said some things that made a lot of sense like that he put more effort into doing things I wanted to do than I did and that is true but now I feel like I made a mistake and I've been having a really hard time dealing with it. Don't really know if I'm looking for advice I just wanted to share it with someone
