Engagement

my boyfriend wants to get engaged, but his ex-fiance has this ring he bought. she refuses to give it back and she wont answer any forms of contact he sends. i really want to help him because he is stressed and sad about it. but idk wht to do. i asked him a while ago if he wanted me to bitch her out. i was serious. but he thought it was a joke. should i ask him again, if he wants me to do something in this situation. because i have things to say to her...

hey i can get ur feeling..you really love him n cant see ur guy so stressed,but whatever b the reason i think he doesnt you to get trouble cause of this,so jus forget this outsider,get a new ring and get engaged soon.this is d best way out to give dat gal an answer n you wil be happy too :) do luck !
