The OW is clearly then using a different phone # to contact you from.
There is not going to be any stopping her.
Changing all your numbers and not sharing with H is most likely the only way to stop her. That is not a good option. H needs to have a way to contact you if for no other reason than your little boy.
More important now to let others know she is doing this crazy behavior. Your In-Laws living next door, are they aware of exactly what is going on in your life? I think they should be, if you haven't already told them. They will keep a watchful eye out for you as well. I am glad you told H, trusting him to take care of the problem you can't. He needed to know just the same.
I think you have a good handle on the severity of this problem.
I am still going to worry about you....
