relationship

so me and my husband have been through alot the years we have been together and this year once again we are killing each other. well I wanted to get away and go visit my dad and step mom who live in a different state (KY and I live in NY) well my husband is telling me that I can go but my son can not and that he will make sure of it. like threatening me I can't bring my son when he wants to go visit as well. I really think we need the time apart at the moment and this would be good. but I also don't want more problems than there already are... I'll be coming back to a death storm if I just up and leave Monday to go down. we are like on the verge of getting a divorce I feel and it sucks and hurts. sometimes people need a change of scenery to get a better outlook.... thoughts?
