I've been reading along and I wondered... I read somewhere that guys like a time, place and purpose. They respond better (I can't remmeber why) something about women not being clear enough and waffling I think. You could try that.
When you were together who was the care-taker of your relationship? I know that you want your h to step up a bit more but he sounds like he needs a little nudge. It worked when you bought the tickets for the concert as it was pre-arranged. Once you start getting into a bit more of a regular pattern of seeing each other more you will start to understand each others needs again and he may well initiate. He may well be thinking that you are too busy at the moment and may not have time to see him. He may be unsure about invading.
You could maybe combine planning a start of an evening/ day and seeing if he takes some initiative once you get into the swing, in an untesting kind of way. What I mean is that fun times may happen organically from that and those tend to be the most fun times when stuff isn't pre-planned by one partner and you work together to create positive memories.
