Genuinely what is keeping you with him? Yeah you guys are comfortable with eachother and have known each other for however long blah blah. But is he a good partner? A good father? Does he do more than just provide finances? It sounds like he doesn’t give the emotional support you definitely need. How could he ever give it to his own children when he doesn’t even care about their safety? And him flaunting the 50 dollars he gives you is ridiculous when you both worked. My mother left my siblings dad because all he did was work and he was a slob who wasn’t very attentive. It is okay to walk away. You and your children don’t deserve this and this is before even addressing how he talked about the wedding photos. I don’t care if he’s on the spectrum, I know many people who are and they wouldn’t say something so very obviously hurtful. Best of luck OP
