The majority of the time spirits do not want to be re-homed because they chose to be with you in the first place.  However, there are times when spirits are with you only for a season; for a purpose of fulfilling something to assist you.  If you feel that a spirit truly does want to be re-homed you should find an outlet where you can find the next person right for them.  An example of this would be the CH Marketplace or eBay.  However, make sure that they truly want to be re-homed and it isn’t you projecting your doubts or insecurities.
