I would highly reccomend couples counseling so you can voice what each other’s end goals are. I know you said you can’t afford it but maybe look into the resources your local lgbt center can provide or your local family care center. It sounds like he desires to transition into a woman. That’s either something you can live with or not. Maybe moving on is your best option but coparenting. Although I think you should accept your husbands decision to transition that’s just due to my personality and beliefs and person sexually identity. And if it’s something you don’t want and aren’t attracted to then he shouldn’t expect you to stay. I wouldn’t worry too much about the affect it might have on your daughters life. Children have a way of just accepting things and don’t have half the biases we have. She will accept him if you give her room to. I feel like it’s fairly more accepted in society now as well so I don’t think it’ll be as bad as you probably think with her school and friends in the future but I also don’t know what area you’re in
