"I am not really sure if I truly want to stay at my Moms or here in my hometown."
Hi Debbie, I totally understand, you can do anything you want with your life whether it is moving back to his town or not.
But still say this to him and just act that way because he needs to feel the experience of you living your own life without him ever seeing you again.
Why should you not? He's untied you to him. He needs to do something to get you to be in his life. Not wait around knowing you're coming back and he can take or leave seeing you whenever.
Do you see? Right now he texts you in the middle of the night, OK, and then when you comfort him and he hears you'll be home soon, he's off to Iraq? He's comforted so now he can stop pursuing.
Just the fact that he was counting on flying away with his mom on your credit and feeling comfortable enough to ask you to watch his house (and dogs) while he flies away to Iraq. There's a lot of Peter Pan flying away going on here. And your always in the picture...providing him with free flights, providing him with a house-sitter. Maybe you could do his laundry while he's away too!
You need to ground him by removing yourself physically in his vision of your availability in his life; if he doesn't claim you, you could be the one "flying away."
