Depends on who is making there need to be a choice, and why, and what this “all” my friends is about.
For example, if an SO is insisting all my friends are bad, then either the SO or I have been a bad judge of who to be friends with, or at least we have very different ideas about it. That really needs to be understood and addressed.
If on the other hand, the “all” friends is actually a group of friends who “don’t like” the SO, I would look at what that is about, and again see why I feel one way and they another. It could for instance be that I am being hypnotized by someone manipulative, or have other “radar” issues. OR, it could be that I am complaining to the friends and just getting sympathy that has them feel that way. Or maybe that group of friends is jealous or prejudiced in ways that I can now see, and maybe I had them be my friends for the wrong reasons – e.g. maybe they are taking advantage of me and don’t want to lose me as a resource.
Or maybe I crave attention and create drama between friends and lovers.
Or whatever. Depends, but it’s a great opportunity to see something about one’s own choices of friends and lovers. There’s probably something you haven’t known about yourself, and this gives you a chance to see it and then do something new, if you want.
