Ok so. My bff and my bf hate each other. I've know my bff for 5+ years and my bf just under a year. My bff wants to hang out with just me but my bf gets upset and asks why cant she hang out with both of us? What should I do?

You need to speak to both of them - individually or together, you pick. Tell both that you're happy that you're friends with both of them and there will be times that you want to hang out with both of them at the same time. If they value your friendship, they will set aside their differences for a couple of hours.

In addition, you need to tell them that you're not "breaking up" with either of them because they don't like each other. That's not how life works. A mature person would "man up" and be nice on the group date and that's how you expect them to act when you guys hang out together.

Also, the bf needs to know that you need alone time with your bff that doesn't include him. It's the same with him. He needs alone time with the guys to hang out and do guy stuff. It's no different for girls. Be firm but nice when you have this talk. Treat this as a life lesson. It takes maturity to a whole new level when people that don't get along can be nice to each other for the sake of their friend.
