Libby I personally would leave it...remember no demands, no pressure...that could make them run back into the tunnel. I would use boundary only as a last resort, if he becomes disrespectful to you and talking to OW in front of you. If the kids know that he talking and texting with OW when with them and if it bothers them, let them tell him. But that's just my opinion, maybe someone else will contribute.
