Fur moms 🐶 please Help!

In need of tips from dog owners. Our dog used to sleep in the bedroom with us. Since December we moved her sleeping area to a different room. It went well. Then we started cutting access to our bedroom. That was a bit harder, but it was going well. Until yesterday. My husband travelled, and It is as if she reversed. She pooped inside the house (we haven’t had a single accident in months), and cried the whole night last night. I even went to check in her twice, I thought something was wrong. But she just wanted to come in the bedroom to sleep with me.

How do I deal with this? We’re really trying to make our bedroom and nursery dog free areas. Any other mama had to do the same? How did you go about it?
