I have decided that I need time to deal with what my life is today, and for the future. And I have found that I cannot do that with so much over my head. Therefore, unless there are issues concerning the children, I will not contact you, and I ask that you do the same for me.
Simple. Succinct. Honest. Direct.
I like it. I hate it.
Did you intentionally leave it open ended, from a time perspective?
Open ended ?
Yes...
Would you rather a nice, long, clingy goodbye ????
Like I said, don't overstate your boundary, say exactly what you NEED to say, and walk away.
