Heading toward affair- what to do?

[hopeOK]

I had my individual counseling last night. She is on board with me having a conversation with him re his "friendship" but she thinks I should wait until after our vacation (that is in about 2 weeks). She thinks that the time together as a family might sway him (we'll be gone 16 days ). I think it could be difficult for me to remain happy friendly but probably easier on vacation then at home.

So with that in mind, I would like to set boundaries for his phone use. My counselor said to ask him to not be on his phone. I thought of saying something beforehand so it is already discussed rather than at the moment he is using his phone to much. Any suggestions on this? I thought maybe saying I'd appreciate it if we could stay off of our phones during the vacation as much as possible so that we can enjoy the kids and the experiences. THEN if he does get on his phone, maybe just getting up & taking the kids somewhere? Walking off on a hike or going to see something else away from him. In the car traveling & at night before bed would be the times when I cannot really get away from that.
