My Girl Has Ornaments With Her Exes Names On Them

Leo and Rebecca Buzz Question....My new girl of 1 year has a Christmas tradition. She buys ornaments with Her name and her Man's name on it. She showed me ours and put it on her tree. Problem is...she has the other 4 ornaments from the past on her tree. yep, ornaments with other guys names on them. I told her she can get rid of those and she was like 'It's no biggie it's my tradition." WOW.....should I just let this go???
