I have a 16 yr old daughter who has a 6 month old baby & she's out of control I recently kicked her out for?

for hitting me & calling me a B- -ch . My mom took her in & is always involved I was determined to not let her in my home @ all not even to visit but my mom was like shes your daughter dont be like that well they came to spend the night last night & even my 12 yr old was acting up saying she hates me & doesnt want to live her. My girls have gone throught alot I have a past history on being on meth & I have been clean going on 6 yrs They hate my husband whcich is their step dad they dont follow rules my 12 yr old wont clean her room its like Im a big joke to them . Did I do wrong by kicking the 16 yr old out? Today she told me she hates me & again yesterday her & I got in a physical altercation My husband is so mad he doesnt even want her visitng at all the house is so chaotic when shes around I love her so much but cant take the abuse. I m also going to remove her & the baby from my health insurance due to not wanting to get into fraud issues if shes not here & she threatens me that if I take them off I wont see my grandson and that I must not care for him. My mom enables her so much Im mad at her too when should I do ??? Let her be ??? this is the 4 th time she goes to stay with grandma and I always bring her back because I miss her and my husband tells me not to give up on her but I just cant deal with this treatment please help!
