I [M/24] Became Way Too Dependent On my SO {F/24]

I met this girl from my previous employer when she was a intern there and we started dating around Dec 2015. Unfortunately due to her visa, she had to go back to her motherland last week.

Before she went back we talked about how our long distance will work and it will not work if we do not have a broad view of our future. I basically told her I cannot do LDR if she does not plan to move to US somewhere in the future. She said she will move to US after about 2 years for me and shes willing to just close her business there and get her prepared for the move.

Ever since she left i became so emotionally depended on her and if i dont talk to her for lil bit like (when shes sleeping) i get extremely said and i always tell her to tell me to show more love to me these days and im afraid its smothering her. I just feel so anxious all the time and I told if its ok to change her plan of 2 years to 1 1/2 year. She basically told me no shes not ready because she has yet to find a job and wants to finish paying off her loan in Korea and when everything is done she wants to make clear cut plan when everything comes in place one be one.

I just want to get an outside prospective on how people feel about my relationship and any advice to reduce my anxiety being away can be great and if she is being fair she does not want to make any clear cut plans yet.

Thanks
