I'm going to cut contact with my best friend of 13 years
Why would you stop contact with your best friend of 13 years?
At this time it seems like a good idea.
Before you decide to stop speaking to your long-time friend, it's important to consider how hurtful this will be for them. They will probably be very confused as to why you cut them out of your life. It's never good when friendships fall apart and it's always good to communicate with the people you care about.
You are right. How about I meet them for coffee?
I think that would be a good idea. It is good to maintain relationships with friends.
