You guys are in your 30's and 40's and some other people sabotaged your relationship and your efforts to keep in touch? I think by this point you both should be good enough to communicate to each other what you want, how you feel, and how to keep in touch. And you dated for a year and he still didn't have your email?
I think how he treated you when you got back was a bit immature, giving you the cold shoulder and all. And now you have to jump through hoops just to for you to see him and he's playing kind of hot and cold. Something about the situation doesn't feel right and I think you picked up on that with your gut feeling. "But you love him." It doesn't mean he will feel the same way and I think the possibility that you felt very alone and isolated abroad has left you wanting more from this guy because it was put on hold and this is what you have to look back on and remember.
You already gave him your number but he still hasn't taken the liberty or the effort to call. I think this says alot. He's got his big important public image to work on and maintain, and probably doesn't have enough time for you.
Keep chasing him by all means if that's what you want but it seems futile.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
