This is my second marriage. The first go around I changed my last name. After the big D I changed my name back to my maiden name. Now I am engaged and my FI wants me to change my last name to his. But I am unsure. He has a sister with the same first name as me, whom he does not get along with. (So then everytime someone says my name I will be thinking of her!) He calls me by my last name and never uses my first name HELP! What should I do? I don't want to hyphenate because my last name would be 15 digits long! But if I keep my last name he will be upset because I changed for my first husband.
