Broke Up with my EX three+ months ago. Is it normal to think still think of what we had and of them?

Broke up with them a few months ago over finding them following some people on Twitter/X. And I kinda felt like I was pulling the relationship for a few months before I finally called it and sent the break up text. This was all online but we have spoke to each other. We were together for about seven months.

So I guess is this a normal part of the process? Like let time heal the “wounds”? Probably won’t give much more info on this so I can keep my private life well private.
