Hi! My mother died four yrs ago from Ovarian Cancer. My Dad is engaged to a woman he met online, who he met three months after my mom died. During dinner a few nights ago, my 13 yr old son asked if he got his fiance an engagement ring because they're technically engaged. He said he was going to trade in my mom's engagement ring to put towards his fiance's ring. I didn't say anything at the time because my son was there but I called him yesterday to say that I didn't want him to trade in mom's ring because its sentimental to me. I'm surprised that he never even offered it to me or my brother. My brother said that Dad can fo whatever he wants with mom's ring but I disagree. Am I overreacting?
