My Girlfriend is Moving

A few months ago, my girlfriend informed me that she is moving out of state.  I encourage the move because I feel she needs a fresh start away from family and friends so she can reinvent herself and be successful.  Well, life happens and her move was delayed.  She plans on leaving at the end of next month now.  People that know she and I are close (they don't know that we are involved) have asked both of us separately, if I am okay with her leaving.  I guess it's because I am her current go-to when things get rough.  As I stated earlier, I am encouraging her to move.  I just have to keep telling myself it is for the best.
