So, as I shared on my last post. HCBM sent DH a text last month telling him she was moving 2 hours away the next day she sent the text (no 60 days notification like is stipulated in the CO) 

She proposed to have my SS every other week, which my DH didin't agreed. He went and filed for a change in my SS schedule and they have the court hearing in December.

After she moved to who knows where, becase she hasn't give us her address, we just know the city, My DH has his son in a different schedule than the one they agreed in court and is been driving half way for custody exchange. 

She sent another text yesterday letting my DH knows that she wont be relocating (face palm) well she is already living 2 hours away, so now she will be back this Friday. I'm pretty sure she is just scared my DH will be granted more time with his son and she will loose child support. Right now they have 50/50 and my DH is the residential parent. He is looking for my SS to live with us and visit her everyother weekend due to the lack of stability she offers. She has 3 more kids that she hasn't see in a month and had move 4 (close to be 5 )times in the last 1.5years.

This change seems very odd, since she was very excited about her husband's new job and suddenly she is back...

How can this change affect my DH from obtaining more time?. My SS is not in school just yet, but will be next year and the current schedule just don't work once school starts. They both agreed that she will have him everyother weekend and she will take CS away, but with her moving back, not sure if that will change everything...
