Wow this is exactly how I feel right now. Four days ago my wife left for a 2.5 month trip to Spain to study flamenco dancing. The interesting reaction from so many people was, "wow how can you do that? I would never be able to leave my significant other for that long." Some even ask me how I can manage to do it. To be honest not managing or dealing with it was never an option. It was a choice that she made for herself to pursue something that made her happy and I could never live with myself if I got in the way of that. I believe anyone could do this, but the trick is finding something that you are that passionate about that would give you the motivation.
