The quickest way to be able to sort something out that isn’t going to plan or isn’t working out when someone else is involved is to talk it through.
This is where email, messages or other forms of electronic communication isn’t ideal. It’s too easy for things to be misinterpreted.
It may not be ideal in your mind and you may fear having to do it, but talking it through with the other person really is the best way forward. It will get to the bottom of things so you can move on.
