So my MIL had a huge argument with my SO last summer and told him I was definitely cheated on him. He laughed and told her she was crazy and to shut up. Well she told her friends and such and bashed me for months and we didn't talk to see them for 6 months. Well she found out I was pregnant at the time she was saying I was cheating. So she told everyone that our 2nd wasn't her sons but she would do the "right" thing and love them anyway. Well my husband told her bullcrap and that our 2nd was his without a doubt. Then I gave birth to our daughter in March. Both our son and daughter have their fathers blood type O. She still claims to this day that she isn't his and that I'm still cheating. So my SO and I decided until she changes her thoughts or stops her crap she won't be around our daughter. We don't want my MIL telling her that her dad isn't her father or any other bull.
