Now comes the really hard part. You have to break up with your friend. In person. Not a text. Not an email. If you live far away, a phone call is okay, but not ideal. Suggest you meet in a neutral place, but not a café or restaurant. As with any breakup, both parties should feel they can leave at any point without causing a fuss. A walk through a park or along a beach is good; exercise and nature alleviate stress, and this has the potential to be a stressful conversation.

Then, as you’re walking, tell your friend exactly what you’re thinking. This won’t be easy, but bolster your courage by reminding yourself you are doing the right thing. Don’t apologize; don’t equivocate. Just tell the truth.

Jonathan, we met when we were both happily married. I tried to be as supportive as possible throughout your divorce, but two years later I find myself increasingly uncomfortable around you because you continue to talk about how terrible all women are, all the time. I am sorry Joanne left you; I really am. But even though I’ve told you I can’t handle the negative rants, you can’t seem to let your anger go. You are such an intelligent and hard-working guy — I hope one day you can resolve this and be happy. But in the meantime, I can’t be around you anymore.
