Long-Distance Relationship HELP!

My boyfriend and I have been together for a little over a year now. I live around 4 hours away from where he lives. We've visited each other on or twice these past months, but it's not something we can do often. It's been fine, but recently we went from having to text and/or talk daily to barely texting. Often, his phone or my computer won't work so Skyping or Facetiming is difficult and frustrating. We both still love each other and want it make it work, but it's so hard and we don't know what to do. Please, if anyone has any sort of advice, I'd appreciate it. I don't want to lose him.
