I so get this:
He sometimes is so confused about things that i dont fault him for his behavior because its like it's not really him.
It's horrible for me to admit it but it is "him", the new him. I am 12 years down the line and it still irks me.
Other times he is fully aware of his actions. Very rarely will he apologize for anything though and that gets very frustrating
I put up with this for about 7 years, the no apology business. He would shrug, say nothing and/or leave the room. I had to stand firm on this, manners cost nothing, and we eventually got it sorted. I had to be clear, calm and persistent in reminding him that we both had to say sorry and when ever I apologised for something I pointed it out to him, calmly.
There was a short period when he started to throw sorry at me for things that had nothing to do with him, things outside his control, and I had to repeatedly ask him to stop. I was like a broken record.
But it got better, slowly, very slowly, over a year of repeating myself paid off. Good luck.
I am trying to get into the mind set of doing for me but it is hard
This is a MUST, an absolute marriage saver, you have to get you own life or you will drown in the pool of PTSD & TBI madness. Get your own therapist, get out of the house, work, play, learn, sit in a supermarket car park and listen to the radio, anything, but get your own life and soon. It works.
Oh, and come here and rant!
