So for the last two years, I have been seeing my son grow up over facetime. After his mom and I split, I moved to South America and they moved back to Germany. In the begining it was almost everyday for months and now it has become once every two weeks of facetime. When we do facetime it's for about 5 mins and he doesn't really want to talk and just starts doing other things. Today, I told him I would be buying tickets to see him for christmas and he just said ok and asked if he could hang up and talk another day so he could watch T.V. This hurt me and made me very emotional, I'm starting to feel like I'm not important in his life anymore. I'm afraid to fly over there and be treated the same in person, not sure I will be able to handle it.

What are things I can do to engange him more and peak his interest. I want him to want to talk to me and not force him.

Edit 1: My 5 year contract is with the military AD, there is no possible way of getting out of it. I've already requested a compassionate reassignment, with no luck.

Edit 2: Thank you guys for the constructive criticism, I will take some of it and apply it. Also a big thanks to those who provided Ideas of how to better engage such as:

Sending post cards, Disney group watch, sending drawn pictures, playing video games, picking up some good reads.
