He HAS committed time to me and does on a regular basis. I guess this is more about my own insecurity than our time together
If he ALREADY gives you guaranteed time together (I thought he didn't before in my initial reply), then I don't know what more you might want that you could ask for that he could be willing to give you at this time.
I do not know if you can change schedules to have more time together. Could you? Or are you at a limit for the time available?
Can you articulate what it is you want? What was Closing supposed to achieve/relieve you of? What is your unmet need?
Some of that "show commitment" thing can only come through the passage of time. You see/know he's committed because... he's here. Day after day. The days go 24 hrs at a time. No more, no less. Can't make them run faster.
