What should do about my "boyfriend"? I WANT SERIOUS ANSWERS FROM PEOPLE WHO HAVE REALLY BEEN THRU THIS!*only*?

I think he realizes what he did was wrong because he went to get help on his own will.. But it is true that things don't change over night.. So maybe it is best for you to just take a short break.. You should still be apart of his life during the break though to help support him with what is going on with his grandmother.. But after a few weeks or months or however long you choose to wait, if things don't get better.. Then just go ahead and break it off..
