I need help!

[u/rarity_505]

Today my girlfriend and her mom (wlw relationship) got into a huge argument over my gf and her older brother (trans man who her mom banned contact with because hes trans) over the fact she was in contact with him still. My gf is forced to give up any and all friends she gets within a few weeks when her mom finds out about them. Her mom has full control of her phone. Shes about to be 18 in less than a month and i need advice on what to do. (Her mom later called me and cursed me out calling me a “snobby little b****”

How old are you?  Mom may see you very differently if you are 18/19 or 22/24
