My relationship with my dp has not been great for a long while now, and tbh we are together for the sake of the kids. I work pt and my supervisor and I have built up a really good relationship with emails passing backwards and forwards all day. I know he would like to start something with me and if I am honest I would with him, but I know it would be damaging to our professional relationship, and of course my relationship with dp. I don't want to be with this guy, just have the odd night of unbridled passion. What should I do?
