Yeah, mine butted into MY room too. I wanted to scream! I did go with a soft grey on the walls because I didn't want to get any color reflection from the wall color onto my fabrics, NOT because he is afraid of color. I went with the closet doors I wanted because of the space constrictions, NOT because he doesn't like the kind I wanted. I did let him put some french doors on one wall even though I wanted the wall space. He is "letting me" put things in front of the doors to suit my needs; he just thought it'd be better for resale purposes, which I can see, I guess and I did it grudgingly.
So my advice is to listen to him and do what you want, if possible. Don't let him get HIS way with everything but maybe compromise where you can. It IS YOUR ROOM. Good luck.
