My boyfriend beats me up and I fell in love with a married man

Good morning my name is Grace I need an advice from you. Pls drop your advice in the comments box.

Please I need an advice on what to do

Someone linked me to this very guy around August 2019 and I decided to give him a chance cause my current relationship has not been going well my boyfriend hits me at any slighted opportunity, he doesn't take care of me, and he doesn't allow me to associate even with my female friends

So it became unbearable for me that I had to give the other guy a chance so we started dating 

He has been so good to me he helped me get admission in fpo he sponsors my education he made me not to be feeling that my parents are poor.

And we're deeply in love with each other.

But along the line I found out he was married, and that my boyfriend that has been maltreating me is now begging me to forgive him

But the truth is that I don't feel anything for him again

And as for the one am in love with he's already married but he's begging me not to leave him

I don't really know what to do

If I quit the relationship it might cause me to drop out of school cause he's the one sponsoring my education

I need your advice please🙏
