Fiance isn't really helping with the wedding planning

I needed this to vent and for advise. This is really coming down to one big thing. It's been months and he still hasn't finished his side of the guest list and im constantly having to remind him. Take it yes, he does work on it, but the fact it's been months is really bothering me. The wedding is 6 months away. How the system works so far is that I normally go out and do the finding and the talking and present him with options. Then he kinda narrows it down. But I'm the one on the phone, doing the emails and research. Even down to our joint bach/Bachelorette trip. MOH isn't really doing that. It got to the point where I just couldn't do it any more after I booked all the vendors. I gave him a list of things to do. Finish the gust list, take care if the tuxes, find a rehearsal dinner venue and book an appointment for wedding bands. But this guest list is REALLY bothering me. It kind of makes me feel like he isn't putting in as much effort and I feel a little dismissed or under appreciated because of it. My fiance is honestly a understanding man, I know if I went to him he would listen. I'm just trying to figure out how to go about it. But it seems like this is a normal thing for brides? How did yall do it. I feel so burnt out there are some days I just want to cry
