Narc Moving On

So, I'm still living with my ex, looking for a new place and things have been unusually pleasant. I'm pretty sure I just heard him talking to his new supply and I'm partially so glad that he's off of me, partially afraid that this is confirming narcissistic suspicions and wondering how far he'll go to sink me, and also trying to not be judgemental but like "what an IDIOT!!! I knew he was onto someone else because he was accusing me of being with someone else 🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️
