Still swaddling?

My son is 6 months old and he can roll back to stomach so we’ve been trying for a month now to wean him from the swaddle. (I know bad parenting but we’re trying) NOTHING WORKS! We’ve tried sleep sacks and swaddling one arm out and he just refuses to sleep unless he’s completely swaddled. It’s stressing me out because he should’ve been off the swaddle a long time ago but he won’t sleep without it. Any suggestions?
