It would depend on the value of the collection.Does it have any meaning for you besides a monetary value??If it means more to him than you,might be better to just let that one go.If the collection has a great deal of monetary value and would really,truly make a difference in the quality of your life and/or your settlement,ask your attorney.I know we can lose perspective on things when we are hurt(i was guilty of this myself when my ex-fiance called off our wedding 3 weeks before the wedding).Ask yourself if having the collection or making him sell it will make a difference in year or two.If you cannot honestly say yes,let him keep it.Good luck and look to happier days.
