There should be an initial exchange of belongings within days after a breakup. If you need help arranging to pick up your things, get it right away. Don’t let it drag on and on. No one is responsible for another person’s things forever. After a reasonable time (a few weeks), a person is legally free to discard someone else’s belongings if that person has not made an effort to retrieve them. So get your things back within a short time of the breakup. Do not ask for gifts back or take gifts back.
