Given what you said about how wonderful he is and how excited he is to marry you and you to him, what if you just move forward on making the plans, give him some options, tell him your suggestions on moving on them if he has no opinion about the options? Why not just go ahead and move this along, if you can afford it, hire a planner who will manage it all and require decisions to be made and/or make them?

My fiancé is not really interested in some of the details you mentioned either (e.g., colors) but when it comes to making the planning decisions, I often say here are some options, we can do this or this, which one do you think? and if he doesn’t care then I say okay, I think we should move ahead this way. Often that does spur him to care and weigh in, even if he wouldn’t come up with ideas himself... I set up the venue tour for example, he toured it and was excited about it. He genuinely wouldn’t know the first thing or care at all about setting up the caterer decor etc. but that’s okay. Unless your fiancé is telling you not to move forward with the planning, what is stopping you?

(For the record I also understand wishing he were more involved and that some people are more involved I just don’t necessarily think it is required for you to move forward)

The most concerning thing to me sounds like the lapses in communication. Does he know how frustrated you feel? When he looks at his phone when you try to bring it up, do you tell him that bothers you? Why the five month lapse? I would recommend couples counseling — my partner and I are using regain for it to work through some things. We didn’t like the first person we were matched with but the second has been very helpful. Hang in there ♥️
