First of all thank you all very much for the replies, sorry that I couldn't respond earlier.
I am not saying I am not to blame or that I didn't do any mistakes. I found myself alone in a new city, so knowing TTATT but still continuing going to the meetings just to not feel alone and develop friendships didn't seem like a bad decision back then (over 10 years ago). Knowing TTATT and still marrying someone might have been a bad decision. But still, she wasn't so good in the truth or else she wouldn't have married me.
So everyone wakes up differently thats a fact and I am not blaming her, really I am not. Even if she would have cheated on me.
So my intention with this topic was just to warn everybody that it can go either way and that somebody you know for many years all of a sudden might show personality traits which were unknown to you.
Our marriage had problems from the start (unrelated to TTATT) just like so many young couples of witnesses have and these problems keep resurfacing and keep getting mentioned even 10 years after. Often I was at a point of giving up but since quitting and restarting is not an option (because its not a video game) our marriage might lead to a divorce anyway.
