Need advice

Long story short, my dad is in need of a place to stay. He doesn’t have a lot of money and is having to move out of his place within 2 weeks and doesn’t have the money to get another place just yet. He is going to have to live in a shelter. My husband and I are well off and are able to let him stay with us. We don’t have kids. We live in a 3 bedroom home and make more than enough money. But... my husband is absolutely against my dad staying with us for a little bit. And I’m so confused as to why. My dad is not a druggie, he’s not an alcoholic, he doesn’t have any issues like that. He’s just a regular man that is just having a hard time, and I am his daughter. He’s always taken care of me. It would absolutely crush my heart to let him be homeless knowing I had the means to let him stay with me. I don’t understand why my husband is being this way. No matter how much I plead and beg, he will not budge. I don’t want to hurt my marriage or cause tension. My husband is my family and I love him. But my dad is my family and I love him too. I don’t know what to do. Any advice?
