Stbxh sees ds6 every other weekend at his parents house near to me (because he moved 3 hours away and it's the only practical option.). He says he can't stay there this weekend so could he stay here. If not, then it means ds won't see him for a whole month. Ds would be very upset by this, as it happened once before that he didn't see him for a month. AIBU to be peed off over this?
