My MIL is horrid

My MIL use to love me until my husband and I got married then I was the devil in her eyes. She said I was holding my husband back, yet I pushed him into getting into his career instead of making the biggest mistake of his life by settling for a job he hated. Told everyone I was cheating on my husband and had two children one of which wasn't his (I have no children and we have no children). She just made up a bunch of crazy stuff. So we cut her out of our lives. Well my husband and I had been trying and finally got pregnant but unfortunately lost our child. Apparently she just found out about both and has been calling up other members of my husband's family asking if they knew we were pregnant and following it up with "thank god they lost the baby, that c*nt is just trying to trap him and ruin his life even more then she already has! We need to figure out a way to get them divorced before she gets knocked up again and f*cks up his life to the point of no return." Luckily the rest of his family thinks she's just as much insane as we do and ignore her calls and tell us about her antics. It just seriously infuriates me at how down right malicious she is! I just needed to vent...
