Can I Marry This Man?

Hello Public, my name is Nana Abenaa and I am 26years old. I am living with a man who is 40years old without marriage, and he has 4 children already before I met him. I also have one child who is living with my mother in the village. This man is a womanizer and he insults me always. So I left his house and only visits him on weekends to cook and wash for him. During those times, I even came to
meet a woman in his room and he sacked me from his room. Later, he came to ask for forgiveness that I should come back.

His mother also came to plead for him and I agreed and came to stay with him again. He still insults me often and even uses bad words on me. He all the time insults me that I have got a very bad smelling vagina and also I am useless in life. These insults keep hurting me every day. But now, besides all these, he wants to marry. Public, do you think I have a good future with this man. Though, I am presently living with him, should I allow him to marry me. I am very confuse, please advise me.
