I'm currently in my second long-distance relationship. The first one ( of 5 years) would have been fine, had he not cheated and subsequently got the girl pregnant.
But while fidelity, determination and love were there - it was grand.
My current relationship has always been long-distance, but it's not
too bad as since it's only 3 hours away AND I work in his city very often. We see each other every other weekend, if not every weekend, and talk several times a day.
It's the little things that really make the difference. Sending little notes and cards, or e-cards, remind you two of your love. Taking special time out of your day just a 'just called to say I love you' phone call. Even, planning to watch a certain show each week, so that it's like you two are watching tv together. My fave: whenever I visit, I leave post-it notes strategically hidden in his apartment so that after I'm gone, he opens up a random shoe box and finds quirky little notes from me! (I got a standing ovation from his boys for that one, lol.)
All this stuff is slightly corny, I know, but it keeps the relationship fun and keeps the love going even with miles in between. Its really all about the work you're willing to put in to making the relationship grow. Dont think of your distance as a bad thing, but moreso as the opportunity to build yourselves mentally, emotionally and spiritually as individuals so that when you come together as a unit - you'll be that much greater as a team.
