I am sorry your in-laws are not there to comfort you.
My in-laws are very supportive of me and the kids. As a matter of fact, H is not welcome into their home until he quits what he is doing. FIL even wrote H a letter and told him he was disinherited--yep-H went a little crazy over that one.
Your H is not ready for parenting agreements, etc.
I would not push this as it comes off as controlling on your part.
Do not even suggest he might be in MLC as that angers them as well.
