My fiance dumped me via email, after having police wake me up in the middle of the night, throw me out of his house, in another state, for no reason other than he decided simply did not want me there. (he has severe mental illness) He sent me the email to break our engagement, changed his phone number and blocked me on social media. I never spoke to him again. He never responded to my emails. He never asked for the ring back. I looked up the law in his state...it is one where if he breaks the engagement, I get to keep the ring, if I break it, I have to give it back. He broke it, in the most horrific manner possible. I don't feel bad about not giving it back. This man ripped my heart out and emotionally gutted me and the post mortem repercussions I have had to deal with this are enormous. I would have rather things worked out between us than keep a stupid ring, but this is minor compensation compared to what I have dealt with. I am not going to argue this point with anyone.
If this was a normal breakup, I would have followed proper etiquette and given it back. No one has the right to judge me on this since you have no idea what he did and what I have been through.
I would like to stick to topic and just discuss the resale question and not rehash my painful personal past
