My toughts this morning were: if he wanted to physically harm me, he would have done so by now.
Also, his out of the blue interactions for the past year or so have been few but always positive. My reaction to them has been garded. I have been cold to him.
The children are telling me as litgle as possible so not to upset me.
But because of the lack of communication on my part, he has no other way but get his info through the children.

I cannot fear him forever. I know how to protect myself. My boundaries are strongly in place and he knows i will take action if necessary.
I showed him that i am strongly independant. He knows my weaknesses and he has not taken advantage of it. He also knows our children need me and he did thank me for all i do for them.

I did not give him a chance to get involved. I get the impression that this is what he wants lately. To be included in the parenting, to be involve more in their lives.
Or it could be thst he is not getting as much info since D15 hardly communicates with him and the other 3 are gone.

I will procede with extreme caution.
I will not contact. I will only work hard at the way i respond and react...
