Why am i accused of being wrong despite of being right?

I had an arranged marriage. My hubby was an only son. My mom-in-law was overly possessive of him, so despite of having a good rapport with me she kept filling his mind against me. He used to quarrel with me over false accusations. This lead to resentment from my side and I even had an abortion. Later when i again got pregnant my mom in law kept irritating me by hiding my things.So I went to stay with my mother. As the baby was born my in-laws kept delaying the matter to bring me back. Finally I came back on my own. This was followed by further frictions at home. My husband by then had gotten fed up of both his mom and myself and had fallen for his lady boss who was also married. Years of mental torture had made me violent s one day out of frustration I hit my mom in law. I knew it was a grave mistake yet i could not control myself. On this she sold the house and went to stay else where with her hubby. My husband grew even more angry with me and also abusive. I could not leave him as I was pregnant with my second child. We lived in a small rented house and there was no help of any kind from him during those nine months.I even got admitted in the hospital alone. Even though my MIL was also ill n between and I was helping her by sending her food. I had even made up with her. but my hubby never forgave me and would tell his sob stories to a female colleague(by now his lady boss had ditched him) whom he called his sister. My Mil staying alone fell on the slippery floor and had a major fracture. I was there for her for 2 months He neglected his mother and kept falling for this sis.After 6 months of fracture my MIL again was hospitalised for upset stomach. Something from which she never recovered.She died an year back. Now he callsme a useless gil for making his mother die alone and keeps on praising this grl fr living in a joint family.
