Frustrated vent

Alex
Let me start by saying I truly think mine is my soul mate and I do not, nor have I ever considered ending this. I'm just frustrated.. 
We're talking future, kids, and houses and we started looking about 3 weeks ago. It's been fun but he falls asleep before I can show him. So now I feel like I'm the one putting in all of the effort only to not know what he wants or what he likes because the response is "i don't care, whatever makes you happy makes me happy" and in sure he means it. I mean I know he means it but can I get some input?!  I'm not the only one living here... And it's starting to cause arguments that I don't want and Im over it. And if I try to bring it up I get so frustrated I start crying and that never helps.. So ahhhh.. 
Anyone else have this or go through this? (He's also sleeping right next to me after in showed him two I think infant to see tomorrow -_-)
