Eating healthy when fam don’t

Do you guys live with others not eating healthy? If so, how do you avoid temptation? My husband buys chips, butter, cookies, and other things that tempt me. I’ve already spoken to him about it and he’s cut out buying a lot of other junk snacks, but he still buys some. I would understand if he was actually eating that junk food, but most of the time it stays in the pantry for a month before I give in and eat it! 😣😔
