I like the suggestion of asking for cuddle time. Touch is certainly an important bonding expression. Feeling a sense of disconnect in such an intimate relationship is disheartening. Emotional intimacy is important, touch such as a hug, held hands, etc is part of that need.
Do you have any topics that are common that you can set aside time to talk about? Might feel forced at first, yet, it's part of that mutual commitment.

How long had you known each other before marriage? Can any of that be rekindled? I mean if you are expected to lead a rather independent life, feeling connected is about the only way to maintain the distance, albeit living under the same roof.
