I hate to be a downer, but I honestly dont think they can in most cases

it comes from a personal experience- but it was a pretty messed up situation, so probably not the best example.
I think it can work though if you BOTH want it enough. If you try hard to make it work, and if he tries hard too, I honestly don't see why it can't work out right?
Stay dedicated, and make sure he is as well- You can do anything if you are passionate about it
Good luck, and stay positive!
