Thanks for the support guys,since this is such a tough decision.
In response to what betz said...we knew right from the beginning that she was the 'other woman' in his life.He was good at hiding it from us before my grandmother's death but once my grandmother was out of the picture,Yen(might as well call her by name)made it well known that SHE this great asian beauty(which I never thought she was...anyway),snagged a married white guy.A married white guy with a government pension no less.A war hero(he was in WWII and 'Nam).In broken english,she would always put my sister and I down as the 'white trash' of the family whenever we visited and there was even a rumor that went around that my grandfather had ordered the plug pulled on my grandmother at the end.Not to spare her any further pain but so that he could get on with his life and marry this woman.It seems to me a little suspicious that they got married three months to the very DAY of my grandmother's funeral,but again..that's just me being suspicious.We were never made to feel very welcome the few times we visted after they got married.Even her children treated us like white trash and made fun of us.I finally gave up and avoided visiting my grandfather after that.I couldn't take it.I guess if I do make a time to go over there and get my stuff,I will try my very hardest to be polite to her.It won't be easy,for sure.
But I promise to try.
