I'm going to demand my fiancee take my socks off for me
Why do you want them to take your socks off?
It's hard to ask her, and I think she doesn't like me and my socks and it bothers me a lot
I see you want help with your socks, but you can't force someone to take them off for you. Try asking your fiancee for help politely.
I think I will leave them on.
I glad then you want to respect her, and her space. You are perfectly able to take off socks on your own, and she doesn't need to do that for you. I think she would be happy to not do that!
