Keep your focus on your kids, and ignore the ex's friends. They can think whatever they want, but it doesn't make it truth.
This is it. The darkest day. The blackest hour. Chin up, shoulders back. Let's see what we're made of, you and I.

You don't have to talk to any of them. You are right, you are there for your kids. If any of them approach you, just smile, and chat. You may be surprised how many of them refuse to talk to your wife now...I know I was, when the men from my son's hockey team started to tell my XH to screw off and never talk to them again.
