IMHO, h's want to come home to there families...no matter what they say. They want to come home. They miss their wife they miss their kids...they just are so afraid and unsure as to how to get back.
I think h does acts of service because he wants to come home. He hasn't filed for d so there you go. Why is he waiting? to see what you will do of course.
He'll come around...have faith. Sometimes my h seemed so adamant that he wanted a d...once went 3 weeks ignoring me but did acts of service through kids only to turn around at hearing and agree to the continuance. Keep your chin up and do what you believe! Don't go off what he's doing.
