<human>: Can you condense the text into a few key points?

I was in the military and after deployment I came back very different. There was this switch that just wouldn't turn off. I was always angry and everything my wife did made me feel angry or like she was trying to always be above me in one way or another.

Anyways long story short I had severe anger issues and I was isolating myself from the people I loved and my wife got the worst of it. So when she wall pulling i was pushing and now vice versa. What really caught me off guard was that I realized my problems and was getting them fixed but the nicer and more caring and open I was to my wife the less she wanted to do with me.

 I recently talked to my wife in person since we separated for 2 months and the talk went well in my opinion. She told me we can meet up and grab coffee and try to reconnect but im just so scared to lose her, we've been together for 7 years married for 4 of them. She told me she's been going out more now getting drunk and high which she never used to do but I know she can take care of herself. What also caught me off guard was us pointing out she is like the old me. Which she then said she likes being that type of person i was the aggressive, in your face, take shit from no one Sergeant attitude .
 
I just want to know when i meet up with her every once and a while what should I be doing and saying to convince her that i'm getting better. Her and her family are the only ones I have due to a really abusive past as a child. i feel if i lose them ill be lost. 

If anyone wants more specifics please let me know I've never done anything like this.
<bot>: My PTSD ruined my marriage and I want to know how to prove to my wife when we meet up for coffee every other week that we should stay together
