How far away does your bf live? Your mom will not get any younger, but neither will you. Ending your relationship may cause hurt and resentment with your mother. If she wants to move, GREAT! If not, come back and visit as often as you can. Skype, facetime, talk on the phone often. It's not the same, by a long shot; but if you're happy, your mom should be happy for you. What does your bf think about the situation? Is there a chance he could or would want to be transferred back closer to your mom? Do you have any job prospects where he is? Moving is a big commitment, but if both of you are ready and willing to close the gap, why wait? Good luck in whatever you decide!
