His gas lighting techniques are so pervasive that I actually went back and printed emails that he has sent over the years, put them together in chronological order so that when I start questioning myself and thinking maybe I did do these horrible things he says, I can refer back to the book and remind myself of past things he has said and done ... including posting nasty comments about me on Facebook.
.I don't dwell on these emails anymore but sometimes if I start feeling guilty, I need the reminder. After a year of ups and downs, I have created a peaceful place for myself, meditating did help a lot- it is new but it helped me get to place of gratitude rather than resentment. It helps that we now live in different countries so I do not have to come face to face with him very often.
I still find him intimidating, I still get a sick feeling if I see his name on my email inbox or worse if his number shows up on my phone, but I am getting stronger and healthier. He still is playing head games with me I am sure but time and distance have certainly helped.
Now I begin every day with a feeling of gratitude and every time I walk into my very modest but MY place, I smile.
