Toxic Parents

My parents are just awful. My whole life it seems like I have done nothing but disappoint them but I'm not sure why. I left my first husband because I was getting beat on a daily basis. That's frowned upon in their religion. Fast forward to my second marriage 8 years later and I find out I can't have kids naturally, so we decide to try IVF, it worked on the first try and I'm now 18 weeks pregnant. My parents were again disappointed stating that my child was not God's Will and was an abomination considering science was used. I hate it, I love my parents but I've spent 34 years of my life fighting for acceptance and I'm just emotionally and mentally drained. My older sibling who got pregnant by a married man however could never do wrong. Her son who was a product of cheating with a married man is the light of my parents eyes and I hate to think our son will have to spend his life as well trying to measure up to their standards. I just want to cut them off and never speak to them again, I just hate I have no family of my own.
