Ex DP is having our son today for a few hours. I am dropping him off but my mum is collecting as I'll be at work. From another thread I'm wondering if ex is a covert narsassist. He has even said before he thinks he has a personality disorder. Any way ex has moved on and he currently just makes my blood boil when I have to communicate with him. How can I grey rock successfully. I'm taking a friend for drop off. Will wear sun glasses to avoid any eye contact. I've instructed friend to not let me talk. Is there anything else I should be doing? I wondered about writing a short blurb to cover any hand over as our son is only 2.
