I want to marry my sister, but hear me out
My sister has a really weak personality and does whatever anyone tells her, she's also extremely feminine and frail.
Two reasons I want to marry her. First, I am really worried some abusive guy will take over her life. I can absolutely see this happening. I wouldn't be able to protect her anymore. Secondly, we're in love. I believe we can have a happy life together minus the kids (but not the sex).
IIN?
