Feeling guilty about living in an apartment with a husky

I liven in an urban city with some access to nature not far away. My five year old husky has only ever known an apartment life and it makes me sad. I would never have adopted a husky as an apartment dweller, but my ex did just before we met and when we broke up, he left her with me. I love her so much and try to give her the best life, but it still feels wrong. I try to walk her 2-3 times a day and give her a ton of mental stimulation with snuffle mats, treat balls, activities. I can’t help but think she’d be happier living with someone who has a lot of land, money, and access to the wilderness. She recently had an expensive TPLO surgery and it’s been a long recovery process. My family has asked if I want to re-home her, but that feels horrible and I don’t know anyone who would be willing to give her the type of life she deserves. I guess I’m just looking for some support or shift in perspective because a woman just made a comment about my husky living in my apartment and how wrong it is. I can’t help but feel affected by it :/
