My first question is: Do all of your friends dislike your boyfriend, or just your best friend? If it’s the former, I would recommend listening to the choir. There’s usually a good reason for unanimous disapproval, and I firmly believe anyone that is not nice to your friends will eventually not be nice to you.

Now, if it’s only your best friend that has an issue with your man, then this sounds more like a classic personality clash—an oil and water kind of thing. This is unfortunate, but you can see why it might happen. After all, your boyfriend and your best friend are the two people with the largest claims on your time. If they are competing for your attention, that alone can escalate into animosity. But you should not have to choose.

If you truly feel both your boyfriend and best friend are keepers (and I would do some soul searching on that, first and foremost), I suggest you sit them down individually and explain what an uncomfortable position you’re in. Tell them how unhappy it makes you. Insist that you can’t—and won’t—take sides. Put it out there that you plan to have the other person in your life for a long time, and things simply can’t go on this way.
