Father in law is sick. Am I being shitty?

Okay so my husband, son, and I live in a really nice house. We are fairly well off. My husbands dad lives in a really terrible part of town and his house is falling apart. He doesn’t even have flooring. He doesn’t work and hasn’t for nearly his entire life. When he was with my MIL, he worked part time briefly and was super abusive to both her and my husband. MIL left him and he went to live with his sister in that house. He’s been there ever since...maybe 40 years? He lives off of his sisters fraudulent disability. Anyways, my husband and him have moved passed everything and they are super close. I really love him and he’s a great FIL. The only thing that bothers me a bit is that my husband is constantly trying to care for him and buy him things. I understand like generally buying him things but it’s like, every time my husband gets something for himself, he wants to get it for his dad too. Think $200 tools. We also pay FIL to get my son from school and bring him to the house. Well my husband wanted him on salary because “we are on salary so it makes sense”. I don’t agree with that. If he doesn’t pick him up, why are we paying him? But I obliged so he’s salary. Anyways, when his dad drops him off, he sits on the couch and lays there with a blanket into the night just watching TV. So of course I feel weird and ask him to stay for dinner because what else am I going to do? The other night, I made my son and husbands plate and my husband looked at me awkwardly and said “dad here I can make your plate....” and I was like ?? Insinuating that I should’ve made it. Like your dad is a grown man. He’s NOT sickly, he’s NOT in bad shape. He’s capable in every sense. It just kind of feels like we’ve taken a caregiver position for this man but he’s FINE. Just broke because of HIS life choices. My husband even wanted to buy him a car! It’s just so out of control and awkward. It’s also frustrating because he can’t pay for anything so any time he’s with us, we automatically foot the bill. He also won’t eat or anything unless you beg him too and talk him into it because he’s “shy”. I’m like listen...I’m not begging a grown man to eat. They do this thing where my FIL refuses and my husband talks him into it or forces him with everything. Even like going on vacations with us.

Well today my husband called me and said his dad was sick and wouldn’t go to the doctor. I’m like okay? Lol. That’s his choice. He’s 59. Capable. Well my husband said if he wouldn’t go then after work, he was driving out there to make him go. I’m like ???? If this was an ill family member or someone who needed our help genuinely then I’m all for it! But his dad is capable. Healthy. Just. Broke. It just makes no sense. Am I being selfish?
