focusing on your own hobbies is a great way to feel better when getting over someone (that's how i cope with losing someone as well).
for me, looking at what went wrong in the failed relationship helps me see what i want to do differently in the next one.
in the case of mistreatment by the other person, knowing what early indicators to look for helps.
you mentioned being in therapy. could your therapist help you find the answers to some of these questions?
lastly, heartbreak sucks. i hope you feel better soon!
