I agree, for the most part. You shouldn’t have to choose. Someone that loves you shouldn’t ask you to choose.
There are common circumstances that result in this, though. Is your friend jealous of your relationship? Realistically, could you be making a really bad decision in your relationship?
At one point, in the past, I walked away from my best friend after her (3rd) abusive boyfriend consistently tried to pit her against me. He knew that I wasn’t tolerant of his behavior, and he made it his goal to get me out of the picture. She continually fell for his crap, so I ended up getting so fed up that I walked away. I couldn’t stand to watch her do this to herself anymore. Doesn’t mean that I didn’t honestly love her, actually it meant just the opposite.
