This is a common Blackistan problem. Trifling family taking advantage of good-hearted, hard-working family. How good, and kind, and sacrificing are you supposed to be? What if he has 2 or 3 more kids? Are you and your mom expected to take them in too because you have a nice, stable home? You have that home because of your wise choices, which included having only one child. You have to protect yourself and your child first. That’s not being selfish. It’s protecting and honoring your life and well-being. There is nothing wrong or selfish about self-preservation.
