Slowly, thanks for posting to me. I get so much from what you write. Thank you.
Quote: I guess I need to also be less available
Maybe physically available, but emotionally available you must be (do I sound like Yoda??). Previously, you were talking about the intimacy receding. If you don't like it, change it. Open yourself to him emotionally. Confide your worries, not about the R, but about your job, your weight, your age, your mother, whatever. Not whining (or as our UK friends say, "whinging") or complaining, but intimate confiding. Lead by example and show him how to be in relationship with you. How would you feel about giving that a try?
