He Goes No Where And He Bores Me To Death

Dear Readers,
I am a 24 year old lady and I have been dating this guy for 3 years now. Yes, he has proposed to me, but the problem is that this guy can?t read and write well?.he can?t even speak English fluently and he isn?t good in bed. Each time I tell him its over, he cries and begs me. Please, what should I do?
