I'm not sure if one ever recovers from losing an entire family.
My ex has said less than 100 words to me since she left this past March.
Only one of my children has spoken to me, to issue harsh words, and judgments through rose-colored glasses that were offered to him by the alienation of my ex, and the woke ideology.
And every day, I look at the picture of them on my phone and I think what the fuck?
I think recovery from this is a great idea to shoot for, but an impossible goal to hit.
The thing is, I begged them to discuss whatever perceived problems they had with me, and they wouldn't and still don't.
On the measurement scale of success, I have failed miserably at relationship.
And I'll never seek another, and I'll never trust another.
Just the way it is
And?
I am sorry you are going through this. Family rifts often seem to follow this pattern where there is evidently an unforgivable offense that remains unspoken and thus unamended and the parties separate. We have experienced this ourselves. Eventually there has been some level of reconciliation but no real acknowledgement of the original issue, whatever it was. We take what we can get even if the relationships never return to their prior closeness. I wish you well. Please don't give up!
