Books about positive “moving on”/discovering one’s self after being heartbroken

So recently I'm been in a "situationship" where I thought it will lead to more but then everything fall apart, silence, distancing, etc.

I would like to read similar book about this but with a motivational ending or self deep discovery lesson. I don't really care about the genre as long as there is a lesson in it.

Thank you in advance and if there are any questions please let me know.
