More gas lighting and manipulation.
If he thinks he'll find a woman who reacts calmly and constructively to finding out he's been going on cam sex sites and has bought images/videos of women on only fans - with no prior discussion/agreement - at all, let alone while she's pregnant and later breast feeding his baby to boot ..... He's fucking delusional.
But I don't think he's that delusional (or if he is, he's lacking empathy to a sociopathic degree).
I think he's just trying to manipulate you, make you anxious, get control, be in power in this situation etc.
He wants you examining yourself, doubting yourself, criticising yourself etc.
He wants you begging him not to leave you and your kids.
That gets things nicely back on the footing he wants things on, with him in control.
As I said, he's a piece of work, and he needs his bluff called. I'd like to see his reaction if you say he can leave, and when is he having the kids. I totally understand why you'd feel you can't though.
I'd like to see him explain to his parents, family etc that he left you because you didn't have a calm enough reaction to finding out he goes on live cam sex sites and was buying explicit pictures of other women on only fans.
Except he won't tell anyone that's why he left . . because he knows exactly how it looks and sounds. He'll lie and lie by omission.
If he's so certain he's reasonable, why would that be
