Divorce & punishing my husband, mil, bil & sil

I have been married for more than 3 years. My in laws were never supportive and humiliated me & my family even my husband for very many reasons. They just need money whether it is their sons or relatives. My late FIL didn't have any money so both the sons were their earning source. I saw no harm in it as it is usual in many lower middle class family. I am from a well to do family and did a love marriage even after knowing every situation. My parents & brother also agreed cause they wanted my happiness. My MIL was after various rituals and stuff though the end discussion was materialistic gains of her and her family. We ignored & agreed to a few. After marriage, her negative comments about her own son started making me agitated & slowly I started ignoring her. Her comments seemed usual and completely normal to my husband as he is being brought up like this. Actually my husband contributes less to his family and my BIL pays them more. Naturally in such materialistic families the son who pays more is the best along with his wife and children. My BIL & SIL used to enjoy these situations were me & my husband got humiliated by our MIL in various situations. My MIL lies about us to the larger family without any boundaries even compares me with my SIL though she abuses my MIL in very many ways in front of everyone. We all stay in different countries but due to daily connection in phones, VCs & yearly visits these things continued growing. My BIL is another weird person. After my marriage, we have hardly spoken. Still it is expected from me to call everyone regularly on weekends even if they didn't welcome me to their family. Though they visited me & my husband and stayed with us for a few days. We did whatever we both can do whole heartedly. This mental pressure of alienating me as I don't even exist is brutal as I have never experienced any thing like this before. My SIL treats my husband like her son but her dressing sense, expose of skin and even touching my husband in a few situation is very improper. Although I took a call and things did change. So it means that I was not wrong. I realized later that my fight for our mutual respect, mental peace & against the emotional & psychological abuse were irrelevant to my husband. Even if tries support me my MIL says that I am complicated. Now I am pregnant but my MIL suggested my husband get rid of it and let me be with my parents as my protest has raised.
