la la la whatever.

I don't think he should be able tell you who you are and aren't allowed to talk to. That's being controlling, and its not a good thing. If yall were not together at the time, it shouldnt even matter, and if he actually wants you to break it off with your best friend hes not worth it.

Sounds like he needs to stop being such a tool and focus his energy on trying to you and your best friend to agree to a threesome.
