My response everytime he threatens to call CPS (and that still hasn't stopped)...go for it! I'll be happy to sit and have a cup of coffee with them in my home. I have absolutely nothing to hide.
When I finally said that, it lost all fuel for him
Be careful... what I think he is actually doing is laying ground work- to tell the courts that there is NO problem.. he see's his kid every day!! If he will lie about you being an alcoholic, etc.. I'm sure he will lie about YOU being there!
I am so sorry but it sounds like you are quickly about to experience what I just did.
Hugs to you. Hang in there
