Its so lovely to hear from you again. I'm so pleased your piecing is still going ahead. From what you describe your H still sounds so much like mine. He always wants to fix everything I say. As for the trust issue I really wish I could help but I've had/am having my own major, major crisis in that department at the moment.
As for your paranoia, I would feel like that too especially as it wasn't a part of his job before the split. Has he actually changed jobs or is it a new responsibility he's been given that means he has to go away? I know how hard it is as my H stayed out after nights out at least once a week for the first 3 months and it did start to make me wonder.
I'm really no help at all right now with the trust or paranoia and I'm sorry because I always felt our sitch were so similar and wanted to help you. Take care IP
