Moving forward together from a mess

[cbtdad]

Also one other thing that got brought up today. Any advice on this from someone who has been through this would be appreciated.
As I've talked about before the W made some friends here in atlanta through OM. W and her have become pretty close. We even hung out with them again Saturday afrternoon and evening. Another couple was there that is also fiends with OM. His name would come up here and there, but it really didn't bother me.
One of the things that is bothering me is that W is still friends with OM's mom and brother on facebook. She says this isn't a big deal. To me I just don't see the point. Everything I have read has said complete contact with OM needs to be cut off. This doesn't seem like that is happening. I'm waiting to therapy to bring this up with W anymore.
Am I making too big a deal out of this?
