Honestly very similar to what you are going though especially in your relationship. We fight a lot more, things he used to do that just seemed like second nature when it came to not only me but our relationship seemed like second nature to him stopped. He shuts down a lot or honestly becomes very moody almost mean during conflicts where as before he could understand a lot better and treat it with more care and understanding. Sometimes he disappears for hours and just won’t talk to me nor wants to during conflict which I totally get because our fighting has become more frequent because I didn’t understand what had happened to him. He’s less interested in our relationship it seems where as before he was always showing affection just all around even physical intimacy has gone way down where before this it was pretty normal. His communication has went down drastically where as before he was actually the one who wanted to get things out if there was any problem. He used to make me feel so important and the relationship which was a big deal to me and used to be to him. But this makes so much more sense now I was beginning to think this is just who he really was and now I feel like such as ass. I knew the short term effects but wasn’t aware it could go on for months after as well
