The backstory is his nephew is 28 years old however he has epilepsy and is not capable of driving or working. He always wants to come visit us however I feel very guilty for not wanting to this. The reason sounds selfish however he just wears me out. I work full time and he never leaves the house. He also has no money and my husband and I are always having to pay for everything. Money is tight and when we go anywhere it is another expense we can't afford so we end up staying in watching tv the whole time. His nephew also does not clean up after himself clean his dishes etc and always hints he wants me to cook for him. This has gotten tiring. It also bothers me that his parents refuse to take care of him. HIs mother has remarried and has moved on with her life. She now has three more kids to care for. His father is MIA and on drugs, is a scammer type of guy who does not care about anyone but himself. I don't know why the responsibility of his nephew has fallen on us. However my husband wants to give his mother (grandma) a break who has been taking care of him which I understand however I have too much going on right now with work, our move to a new place and I am also battling health issues. How do I approach this without seeming like a cold hearted Karen?
