Guilt for wanting to live my life?

I will be getting married and moving with my husband to his state which is a two hour flight. I am ready to branch out and be free since I am over the city I live in. It’s too expensive and I don’t have many friends. The thing is I am so so close to my father and he has an illness. I am always there to take care of him and worried about something happening if I am away. A big part of why I want to also move out is so my father can explore this new beautiful place and have a place to always travel to and hopefully possibly move there too. He will be retiring this year and has plans about moving back to his old country. His wife isn’t very helpful at all and it really angers me. She is barely ever with him. What should I do?
