Yes, I do believe long distance relationships can work but both parties have to be honest, devoted, have open communication among themselves. I can tell you if one person is insecure it will never work no matter how hard you want it to. Many people have long term relationships..whether it starts out that way or because circumstances have made it that way. Its what you want from your relationship and if you prefer for it to be local or long distance.
Communication is the key. Skype, Yahoo IM, and other forms of communication. Without it love dies. It is hard to sustain... be advised. I've never been able to make it go very long. I wish I could... there are some terrific women far away from where I live.
