Have you had to exclude some family due to mistreatment?

Virginia

First off let me apologize it is long to start off and all the grammatical errors. My step mom has decided to be the negative one in our family. My sister moved in with her two children (had no other choice) on my step moms idea that it be good idea. However she is constantly complaining about them living there. She bad mouths my niece, nephew and my sisters parenting constantly. Saying a two year old (she just turned two) should be speaking clear english and should be potty trained by now. Also that my nephew who just turned one should be walking by now and not crying because of his teething. My sister cleans, cooks and got a job and taking care of her children. Pretty much as if they weren't even there. She makes my son her favorite grand kid ignoring the other two. Also she said I shouldn't be having this second child because we aren't married, I'm not working and give it up for adoption. A few weeks back I asked to be able to watch the kids at pawpaw and Gigi's house. They don't have stairs as I do and the bathroom is up stairs and we are potty training. I am 27 weeks pregnant and getting around has been hard with my 8 month old, a 1 and a 2 year old (my step mom is GiGi) said sure but this is house isn't a baby sitting house. I said fine. Then she said while I have you on the phone I am going to complain about your sister. I said why do you do this? Why do you have the right? She said I have the right because I have you on the phone and some young 26 year old shouldn't be telling me what to do. Then she goes off to say how we need to buy a house, a better car and how I should be parenting my son. Also how he shouldn't be 27 pounds at almost nine months...pretty much calling my child obese. I said I don't want to hear it. I'm tired of it. If you have nothing nice to say to me or anything about my sister don't bother talking with me. I didn't cuss. I was calm but I was done with her bullshit. I am the only one in my family to stand up to her. She is expecting an apology...it ain't happening. We have decided that since she is acting like she is innocent in all this drama our son will no longer see her or consider her a family member. My dad/his pawpaw will be the only one invited to things and spend time with our son. She says she loves her step daughters and grandbabies...... Sorry gals I just had to get this off my chest. My poor boyfriend is on my side but my hormones make me crazy and he eventually zones out..love his heart.

So have you had to exclude a family member from your life or child's life?
