I've noticed that over time couples get into patterns of what they talk about (work, kids, money, vacation, practical matters, etc.). When you were first dating and so curious to know everything about each other, your range of topics may have been broader, and I invite you to get to know each other again.
On your weekly dates, leave the daily topics behind. While it may be a struggle at first to talk about more intimate topics (yes, this may include sex, yet intimate means more than sex), it's worth it. We do have to work on our relationships. While fairy tales say, "and they lived happily ever after," I haven't yet met a couple that is living happily without talking and creating intimate connection.
"101 Things I Wish I Knew When I Got Married" covers the range of topics that can lead to happily ever after.
