Heartbroken and confused 😔

My husband has told me he only loves me cause I’m the mother of his kids (15 months old and I’m 26 weeks pregnant). He wants to stay together and pretend for the sake of the kids but I’ve told him I can’t do that cause I want our kids to know what love is and frankly, he talks to me like shit and they shouldn’t think that’s okay. My parents had a lengthy court case and absolutely hate each other’s guts so I know what that’s like. I seriously thought things were good though... I feel led on and heartbroken. He thinks nothing could change though but I think if he got help for his anger and mental struggles, it could improve but if he doesn’t see the potential for change I know I’m fighting a losing battle and honestly I’m done fighting for us. I just wanna know what I should prepare for, mentally? I’m 24 with 2 kids and nothing else. I’m scared to tell our families. I’m so scared and sad... will I be happy ever again? Will my babies be happy?
