I wouldn't worry too much about this little backslide. You know he is better when you don't contact him......it's frustrating but it is his style. Also, he often seems to be a bit 'off' after a hunting expidition. Do you think there is one particular person with him on these trips who is against marriage?
To be honest, I think this lifestyle your H has just suits him down to the ground. Intimacy when he phones and wants it and freedom when he wants it. If it works for you both then run with it.....but don't forget what's sauce for the goose is ALSO sauce for the gander.....you use YOUR freedom and go see your aunt for Thanksgiving. Let your H see what it's like not to have you there.
The way things are constructed at the moment your H has no real responsibility towards you emotionally and no-one questions his comings and goings. This situation is so entrenched I just don't know what would make it change. Maybe he is waiting for both of your D's to be gone so h can have you to himself....or maybe he just likes it as it is and doesn't want changes. Does he EVER talk to you about the future?
