Can someone help me with My girlfriend parent issues?

Well I have been with her for 5 moths now and she is really hurt, she lives with her mom because her parents are divorce, she hates her step dad but can't be with her dad because he lives too far away, she is really hurt to the fact that her mom doesn't want her to be happy, she makes everything up to not let me see her and my GF say is because I'm

Wealthier than them and believes that my GF is only with me because of that but honestly is not true, she feels like she to nobody but me, she has 2 older bothers, 1 younger sister and lives with her mom, she needs her moms love but doesn't receive it, she is really hurt and I want to move her out from her mom to a place for us but she doesn't want to leave her mom right now, what can she do to receive her love that she needs?
