Hi Harry,
I'm can't add one thing to ITL and sickofit, since they've so obviously hit things on the mark for you. I just wished to say it was awfully good to read you went directly to the stuffing of the matter in your reply, without pulling any proverbial punches, here. Not that I wish you to be too hard on yourself, either, since guilt on anyone's part obfuscates healing across the board but so does avoidance of dynamics, you know?
I do wish you the best with this. After my trauma(s), I was married to someone who pretty much compounded things by actually impeding the healing in various ways. His was deliberate, yours does not sound as if it is and you sound like you wish to approach things from another direction. That's a lot, from my perspective and for what it's worth.
I've been stuck in some terribly destructive PTSD behaviours in the last 20 years. Guilt is awful awful awful, and worse because I have children, 3 who got to live through most of 'all that'. Also for what it's worth, they are good, kind, successful adults. 2 are through college, one has his Master's, a wife and baby, the other working on his Masters now, a third looking at med school. These are not just superficial successes, either, since they are also good, kind people without exception, even looking at them objectivly. All 3 have been treated for anxiety disorders, one is on-going. I do not know how to be more sorry than sorry for that. I had some help getting them that way, I know, with the person who caused the trauma but in my head the fault is all mine, The bottom line, however, is that they really are ok, as adults.
I think another point is that you could give your children a bit of a lead on things, you know? More than a bit. With a new approach, "spirit of healing" your children will see the support from you, and not the blame, and follow. It's going to make a huge, huge difference. Please do find a T who can help all of you help each other through this. All of you so much deserve it, and the peace you'll get from this.
Please excuse how long this is. I just kind of lived though having children while coping with PTSD, and was married to someone who actually used it against me quite aggressively. He refused to become informed since all he wished for was a weapon in a power game. You wish for peace in the end, I think.
Do take care,
Anni
