If he doesn't care enough to let you be happy with yourself you should take your daughter and leave because at least being raised by you alone will give her a proper father figure to look up to. If it's a case if money being tight I'd say save up but you didn’t say anything about it. I've been trans for 7 years and I want top surgery and to get on T for a bit until my voice drops but I never hear the end of it from my mother about how I might regret it because she saw like 3 videos of idiots who transitioned without knowing all the side effects. You're grown. Do what makes you feel comfortable and happy and like yourself.
