Did I really abandon him by leaving?

So we’ve been together 7 years, two kids, been talking about getting engaged for a while. Lately things got… heavy. He started saying he didnt want kids anymore, said he felt trapped. Then one night after a fight he screamed that he never wanted this life and blamed me for ‘forcing’ him into it. I was shook. Like, we both agreed to this. I’m the trans guy, he’s cis, and honestly lately I felt like he resented my transition. Not in a mean way, but like… he stopped touching me. Stopped calling me by my name. Started calling the kids ‘his and hers’ instead of ours. It creeped me in. Last month he went to visit his fam in Florida and I packed up the kids and went to my sister in Warsaw. I needed space. Now he’s saying I abandoned him and that I’m punishing him. But I just needed air. And now he’s sending texts like ‘you took everything’ and I feel so guilty but also… like, what about me? dont know if I’m the villain here or if I finally stood up for myself. Need real talk.
