Let's just say that you and your SO are having major problems and that you've been together for years (many, many). You are on the verge of ending it all and you ask him/her, "What can I do or change to make this work?" and he/she says, "I can't stand your personality. You would have to change that." What would you do? Would you change your personality to be with someone? If so, how would you go about doing that? Or, would you decide that it's completely not worth changing yourself that much for someone else?
