1. Enjoy the relationship while it lasts and try to mentain the relationship.
2. If it has to end, just let it go. There is always better person for me.
I know it sounds easy but in reality it is so hard to let go.
While my wife was still oversea, there was a difficult time my wife (my gf) thought of leaving me because she did not feel safe for us never met and being together. I hold on and did not let go. I felt very hurt to hear all the things she had been saying but tried to not let go. Fortunately, my wife changed her mind after few weeks. We met each other, got married and both are here happily now.
