Diablo is right, if you are not allowed to speak about your feelings, he is not worth your time and emotions.

Shayna made a very, very excellent point - pushing someone away because being angry is less painful than being sad - is something I myself did. It was with my r/l hubby who is also my Dom, during a time where we were long-distance for job reasons for 2 years. It very nearly killed me inside. Thank God he realized what I was doing, and reacted accordingly.
I know nowadays that I would not be willing to enter in a long-distance relationship anymore. I simply cannot handle it.

I am not the sort of person who could survive with a just-online partnership for long. If things get intense, I need real contact. Sometimes just for a god damn HUG!

I have a kid myself, and once you are responsible for a family, just moving to the other side of the planet and giving it a try is not an option anymore, or at least it is not as easy. (I think in such a situation it would be better for the non-having-kids partner to move to the one with kids, as changes and moves are easier for a person without kids!)

True, one might find the perfect partner very far away. But, in times before the internet, we also tended to look for a partner in our close proximity, and it worked.

If I were you, I would try and discuss with your Master if his needs/expectations for this relationship are the same as yours, and try to get real. Anything else will make you very unhappy, I think.

Should it turn out he does not want that, you should better look for someone who lives closer in the future, to avoid that problematic situation... it´s just my opinion.

I wish you the best of luck.
