Quote: one of the reasons I am in my current down on marriage mood is my H guilted me out of visiting my sister for a week.
I don't know all the details, but this is bothersome. H may be selfish and immature and make unreasonable requests. I think it's important for you to acknowledge your choices. You chose not to go on the trip.
H may be giving you some lousy choices, but be careful about playing along with his game. There's a difference between choosing to be loving, regardless of the response, and enabling someone's immaturity.
