Men are usually not the best communicators.On many occassions Ive worried about the distance between my husband and I, but in time things always settle down enough for us to talk.
When the kids get older and become more independant the house quiets and we wonder what the future hold for the marriage.......its so different without the kids,I at least built a marraiage on the family concept....its hard to switch gears.
Change is weird and unfamiliar.....we all go through it though.All the best.
Have a good day Onyx
