My boyfriend won't move out of his parent's house

25F, 27M. He makes 6 figures and has been promising to move out for the past 10 months we've been dating. He has plenty of free time to house hunt, it's purely out of lack of effort. He's a good boyfriend otherwise and very kind person, but I've been so irritated over everything lately and feel like a monster. I was once determined to marry this guy, but it's like all my feelings for him vanished so suddenly. It's like when you can't eat your favorite food anymore. Sad!

While living at home might not be a big deal for some, I feel like I can't take him seriously anymore if he's unwilling to make moves that are well within his ability. I moved away from home to a more expensive area for him, but he won't move out of his parents house for me? Why is your mother still making you dinner every night?

I told him on new years if he didn't enact a plan I was going to end the relationship. Obviously between the ultimatum and relationship posting on reddit it's already joever, but does anyone have advice on how to navigate this breakup fairly or if it is really is normal to live with your parents as a 27 year old white collar man before I throw away the healthiest relationship I've ever been in?
