To stay strong in the relationship or not?

If you were promised that he'll make it up to everything he has done to you, would you believe it? He promised it before and i see no changes since he got home from another country. His main reason of leaving his work is because of us i dont see it now i mean i cant feel that we are the reason why he wanted to left his job cause all he say is he he is bored he had nothing to do to think that we are four people in the house including our 1 yr old son. I cant see the sense i cant feel it he never make up with his promises, we argued about this cause for so long he had a mistress other woman aside from me . He beg for forgiveness told me that he'll leave the girl but he didn't it last for over a year i still forgive and forget im holding on to his promise, i told him about it, in a nice way a very approachable nice way but it went to an argument he never understood why, maybe beacuse he is guilty cause he is not doing whatever he promised to me then he became very angry though im just stating the fact that he always say that he is bored though he got all his life to help me and my mom take care of his son cause i need to do other chores like doing the laundry and cooking cause mom is already old shes 65 years old now and i dont think that my mom should takecare a lot of my son if my husband is already here with us. Then he became very angry and he dont wanna talk about it well i told him yes thats all hes got, to leave the house cause hes guilty of all the things i told him i asked hi nicely not to leave, and he have thrown me away from the door like ten steps away i just cried at that moment and then he almost broke my left leg and my arm, i cant do nothing but to cry cause i think i just hve enough of everything iwas abandoned by my family beacause of him i fought for him for our family i accepted everything about him the fact that he already have a son before ours from another woman iaccepted him whole heartedly i just dont think this is gonna work out for us, i just really need to vent it out. I have no one to run, its 2 am in the morning in my place nobody can give me an ear to losten to my burden. Im just so fucked off. I am hating my life and myself.
