Am I wrong for not letting my mom move in with me?

i am 19 married have a 1yr old a house and go to school full time. A while back my mom asked if she could move in with me. a lil background info:
1. we do not get along
2. she was very abusive (physically and emotionally) to me and my sister
3. she has done drugs and attracts bad people into her life
4. she has no job and never has and got her lisence suspended
5. out of my whole life i only lived with her for 1 year (worst year of my life)
I know she gave birth to me but i really do not want her in my life am I wrong for not wanting her near me or my family....
