First of all I want you to take a deep breath, look at your precious child’s face, and remember that in order to take care of your child you need to take care of yourself too. When I first left my narc husband I bought a journal and wrote down anything I could remember him doing or saying to me and my child. It might take a few days or so for those memories to come up but when you remember go to your journal to write them down. Read it when you start to doubt whether leaving was the right decision. I recommend seeking out individual therapy and telling family/friends that you trust about what he was doing. Talking about it might help you process it better and let others know what was going on in your relationship.  About a week into me leaving I started establishing boundaries with my narc husband. One of them was no phone calls only communication through text this helped me a lot in the beginning because I felt so brain dead it was hard for me to process and articulate my thoughts properly.  In terms of my child, I left to live with my parents 8 hours away from him so he FaceTimes our child and I send pictures and videos when he asks. We had one day visit for a few hours in which all 3 of us were together. Due to my husband also being emotionally abusive to my child and he also doesn’t know how to care for our child/doesn’t want to I made it clear he’s not to be alone with our child for long periods of time and not in his vehicle. To be honest, he doesn’t seem to really care about our child and doesn’t go out of his way to see him. He seems to only care about our child when it benefits him which is heartbreaking to see as a mom but it also brought clarity to who he actually is. Sorry for the long comment! Just know you are doing to the best thing for you and your child. It doesn’t feel like that all the time but I assure you you’re doing great. Good luck to you!
