The mother of my girlfriend is crazy

Helloooo, talking a little bit of my life, I have a girlfriend! We're been together for 1 month, everything is so new cause I never had a serious relationship before and I love her so much, shes too pretty, but she has insecurities and I don't know what to do :(

I know I cant do much more than just support her, but I wish I could more than that, because I don't wanna see her sad and repressing herself, I want her to feel free, but that is so much difficult because of her mom. 

Her mom is very close mind, my girlfriend is a trans girl and her mother just don't understand what's going on with her, and even if she understand his identity she'll say transphobic comments anyways, such as "don't dress up like that outside, theres familys around" 💀 because she already say that kinda things and I don't think the situation will change after she comes out the closet because even if she wasn't a girl, whats wrong with a guy wanting to dress femenily? So I don't think she will change any soon. 

Leaven that behind, I have problems with her mom, she just thinks I take the money of her daughter just to buy me thinks, but it's just not true. My girlfriend stays to sleep in my house too many days in a week, and my family doesn't have a good economy so we ask her to contribute with THE FOOD, THATS ALL, we're not asking her for buying us expensive stuffs or smth, and if she get out her house with too much money and comes back to her house with nothing IS HER PROBLEM NOT MINE, she just doesn't have controll 😭 and is not my fault hag get out of me! (I just learn a new word, I didn't know hot to call a old woman disrespectfully) 

So byeeee <3
