<human>: Can you provide a brief overview of the text?

Me and my GF of 4 years on and off are having some issues cause money is tight like most people.

Me and her lived with her mom for several months and now her mom is moving and for her to continue her schooling (which i want her to do/fully support) she need to stay close so her solution to that is to move back in with her ex-gf [29F].

This makes me uncomfortable because her ex is and abusive person both mentally and physically but she has no other place to go due to our money situation I will be moving back in with my grandparents who will not allow her to stay with me even for schooling purposes and trying to save up money for us to live together but until then what should i do Reditt?

P.S. My GF is prego and she is still in a lease for the apartment with her ex I am considering buying her ex out of the lease is this possible or would this be a good idea?
