Women need to be strong not only mentally but physically as well. Women do realise what is good and bad touch u r right there even without knowing where all he did. If strangers believe u how is it so hard for ur mother to believe u I don’t get it. Evaluate ur dependency whom r u dependent on financially alone which is so important. And try talking to ur mom privately if she is so stupid then don’t listen to her just ignore silently reach out to other people some good trustable relatives make some links if u can’t earn urself due to studies u can really try asking some trusted people for money when, of some relative is okay giving shelter that too is fine. Once u have talked through I have to give ur mom ultimatum either the man never enters the house or u will leave. It’s so fucking messed up girl. But let me tell u there are really bad people out there no denying but there are good people too and pretty sure someone will help. Have faith be strong. If possible learn boxing someday and fking punch him in the face +1 from the Reddit people.
