My partners mom.

Me and my partner want to have a baby in the future, the only issue is his mother, he doesn’t trust nor like his mom, and I absolutely don’t trust her if we were to have a baby, she is extremely manipulative, controlling, and every word that comes out of her mouth is a lie to get attention or she just exaggerates the truth. She’s telling me I should only have one baby with my partner (her son) and she’s trying to tell me that we should only have a girl. Keep in mind she is extremely verbally abusive and lashes out horribly when she’s mad (she has broken and thrown away my belongings as well as her sons) when we do have a baby I don’t trust her with our kid, as she has known to have family attack everything we do, what can I do? By the time we have our kid we will have moved away to the state I used to live in before moving in with him, and that already is going to start trouble with her.
