You are doing brilliantly OP but I dont think you're quite there just yet.
There are several points that grab me.
I believe you are a rape survivor? So sorry. Me too.
You were I'll enough to be admitted
You are very intelligent
Maybe a weight issue? (I think I read that)
Lack of support from mum
Obviously in therapy
This man has NPD. He is an abusive monster.
Therefore, you are firmly in the FOG.
Egg-gate has attracted much attention. I will tell you why it happened.
In that moment where you jockingly called him a name, what you ACTUALLY did was provide Challenge fuel. And you wounded him. You said he was 'seething'. Yes, he was. So he had to exert control. Hence the egg.
When he failed to get the response he needed, fuel, he quickly retreated. Doleing out an Absent Silent Treatment to 1- punish you and 2- Remove himself from you in case you elicited a further wound.
Does that make sense? So egg-gate was PIVOTAL to you beginning to join the dots.
Other pointers are black/white adore/abhorred thinking.
Isolation - standard
Victim? - Bet it's there...
Vulnerable woman? Yep, you are
Laziness - standard
Low level negging, quips, put downs - standard
This man has a personality disorder. No therapy can make him change long term or even make him aware of it
Breaking things with absence of physical violence? Highly indicative
His toxicity will already have started to effect the children. He needs to be removed. Immediately.
Also, it's very difficult to make progress in therapy if you are in an abusive relationship. Just pampering over the cracks.
You've been through a lot and suffered a lot. You dont need to keep on suffering.
