That's definitely a hard situation, but I agree with the others that have commented on this. In my opinion, this experience will make your relationship stronger. I left to work abroad when my boyfriend and I had been dating for 4 months, and I was abroad for 2 of the 3 years we have been dating. It's hard, but not impossible. If your relationship is going to survive marriage, then it can survive this.
Also, REALLY hoping the rumor about all of us finding out before April 15th is true. This wait is killin me!
