Advice needed please...

My BF doesn't have much family... his only living relatives are his sisters. One of them is currently on Meth or some other drug that we don't want our children around and his other sister is constantly calling looking for help or some kind of charity. (I'm not working and my BF and I are currently living with my parents bc we can't afford to live elsewhere.) I feel a sense of obligation bc they're all the family he has but I don't want the drama. Am I wrong if I don't invite either of them to my baby shower?

**UPDATE** Neither sister will be invited. My decision. I don't want the drama. I'm not even inviting my OWN sister for that reason.
