If you are wondering why I’ve replied to all your posts, it’s because I’m concerned. I was married to a sociopath. Not my diagnosis but two independent psychiatrists. He was very charming and did not have a jail record only because he talked his way out of it. This was back in the eighties when domestic violence was not taken so seriously. If he was strangling his mother that’s high high risk factor. And stalking his wife that’s another huge red flag. You being pregnant puts you at high risk. I urge you to get help breaking away from him.
