One month! That's a pretty long fucken time. I'd feel guilty leaving for a month and would never do it. My ex would have lost her mind considering I felt all that you described being away for 48 hours. I used to have the house clean, laundry folded, yummy food simmering in the slow cooker, and the fridge packed with food before I left for two days, and I'd still come back to guilt-trips and the sky falling.
