Yeah they are masters at the silent treatment. MASTERS. They can go days, weeks, months and even years doing it. They can also pop back in whenever they’re ready like nothing ever happened. It’s not about you, it’s about them and how useful you can be to them. The covert narcissist I dated for a year, it took me awhile but I sorta figured out her patterns. Every 6-7 weeks she would devalue me and discard me, I didn’t always know the reason but the timeline always matched up to 6-7 weeks. She’d gaslight me into starting a fight so she could use that ad the excuse to ignore me. In the beginning it lasted for 12 hours, then it would go to 2-4 days, then it would go to a week, then a couple weeks, then the final discard lasted a couple months. She ended up popping back into my life wanting to meet up and talk, even though I’d been pushing it and was getting ignored so I dropped it. It had to be on her terms not mine. The meetup had to be her idea, and it seemed normal for awhile again but it was all a play. She ended up discarding me for good not long after that and I haven’t heard from her since.
