First time on here and I’m after some advice. Been with my partner 4 years and I have 8 year old son from previous marriage. We don’t live together but spend time in each other’s houses. At his last night, I had made dinner for the 3 of us. Messages between us were fine, he got home and all was fine. We sit down for dinner and he’s given me a lot more than I wanted. I said I didn’t want that much and had purposefully given myself a small amount. He then throws my dinner back onto my placemat. I took offence to this and said I would eat in the kitchen as it wasn’t nice to do that. After I walked out he slammed the door so loud I thought he had broken it. Then stormed around swearing and saying he was leaving. He didn’t, just shut himself in the front room ironing. I went to check on my son who was still at the table, he was shaking and crying as he was so frightened. At that point I knew I needed to leave to protect him, which I did. My partner is not violent and would never be so but his behaviour was so unusual and so volatile I had to leave. Not heard from him since and not sure what to do. Any thoughts? I’m just so lost with all this and need some advice.
