Is this Healthy?

Ok, so I met this guy at the Jefferson Armoury in Edmonton, Alberta. We immediately clicked. We were being sent to different places and he was going to be gone longer than me, so I didn't get to see him on my return trip. We talked a lot while I was in Manitoba, and on my way back to Edmonton, we started dating, he asked me out over the phone. We've now been dating for 4 months. We don't get to see eachother a lot with work and football, and school, but we try and talk on the phone every night. Is it healthy that we are doing long distance? I miss him a lot, and when we fall asleep on the phone and I can hear him breathing, it's almost like he's next to me. Everything is great, but is being long distance like this healthy?
