<human>: For some background, I found out roughly a year ago that I have a brain tumor. It isn't growing out causing any issues in my daily life but that could all change at any time. Even though it doesn't pose an immediate problem, I still feel the need to get my life together as best I can.

One thing i had to do was tell my close friends and family about my situation. This is where my friends enter the equation. I told my friend and his twin sister because I have been friends with them all my life; I was part of both of their weddings. But They don't get along with their family all that well.

This is where the problem arises. They both got married within the last four months and since I was part of both weddings I was spending a lot of time with their older sister. It was too the point where their extended family was completely convinced we were a couple when they saw us at the weddings.

She and I were open about our feelings and the feelings are mutual. The problem in running into is good my friends feel about the situation. They've said that their family keeps trying to set me up with their older sister. And they have both hinted at their displeasure at that idea because of their relationship with their family.

I wouldn't even think about pursuing a relationship with her without talking to my friends first. And I wouldn't do it if they weren't comfortable with the idea. But with how well their sister and I connect, the idea of not pursuing it is painful.

<bot>: Developed feelings for my friends' older sister. They have a rough relationship with their family and probably wouldn't like the idea of me dating their sister.
