Heartbroken and needing help!

[irishblessings]

I feel like I am talking to the wind here - but it helps anyway!
I call H tonight to let him know that he is "losing" S - not good interactions.
H says that he knows but that "he does not want to be with me!!!!!!!!"
I said - I am clear on that.
In fact - I actually say " I am clear on that "Joe" (fake name used on phone chat line) -
"43 years old" -
To which H says "I am hanging up" which he does!
OK - so friends help me - do you validate an MLCs "reality"? I realize that he is pissed right now - and that I need to completely go dark - but do I need to explain that to my 16 year old S = so that he understands?
I am never going to get through this!!!!!!!
