Wow.
No offense, but your husband is being a jerk.
I'm in bluntly honest mode today.
With my kids, mommy's room was the center of the house. Always.
My kids never co-slept or anything unless they were sick and needed to be right by me, but still....everybody on mommy's bed or in her room.
My husband was no fun at all. In fact, he was mad and yelling most of the time.
We had what my daughter called "Happy Hour" every night in my room before bed time because dad was always in such a crappy mood.
I don't know....
My kids were always so good because if I was really sick, they were so easy. They would stay right on my bed with me and watch a movie or something so I could rest.
My son is 14 and he still loves my bed. In fact, he says I can't get rid of it, ever, and if I do, he wants me to give it to him when he's grown up.
I don't understand why your husband gets so ticked.
I mean, 18 and 12 and still co-sleeping or something I could see him not liking, but your kids being in your room? In general?
I would tell him to make sure there's a bed in his "man room" if this is how he's going to act.
I honestly don't know a single person that was never to be allowed in their parents bedroom. Especially when there is another parent in there.
I hope you get some good advice, but I'd come right out and ask him...
"Seriously...what is your problem?"
