Do Long Distance Relationships work??

Ok so me and my man have been together for almost a year. Head over heels for each other, treat each other with respect and just enjoy each other in general. But here’s the problem. He travels a lot for work. Every 3-4 weeks he has to go away for 5 days, 8 days or 12 days, depending on the project. I knew this when I met him, knew it would be part and parcel of being with him. But when he is home, there is about an hours drive between us ....

so my question is this .... do long distance relationships really work when you don’t get to see each other as much as you would like to? How do you keep it alive until you make the choice to be together and one of us has to move??
