XH contacts kids:any thoughts

[peacetoday]

so XH or OW wife contact D again via message FB

still feel it is OW doing it
Just not sure why
I think if XH was doing it he would be more aggressive with initiating a real phone conversation

they asked how her halloween was?

she didn't respond
she already told him to send his number when he is ready to talk
she does not intend to have an email R with them
any thoughts?
