So DH works VERY long hours in a very stressful job, I get this, I understand it. He tries hard to make sure we spend time together at weekends and more often than not it's lovely, however when Monday comes around and he's back in work mode it's like he switches off from me, It's like he goes into a mood, he's quiet, disengaged, not affectionate - the rational part of my brain knows that he is super busy and just in work mode but it still leaves me feeling sad. I try to be pretty constant in my mood, I'm generally upbeat but find it hard when I'm met with monosyllabic answers and just generally made to feel like I'm annoying. I've tried to talk to him so many times about this and he sort of gets it, tries for a day or so and then it reverts back.
