I understand where you are coming from, and I tend to agree with the worry that if you've already broken it off, perhaps you won't be dedicated enough for a long distance relationship. I tend to at least try to be logical and rational, especially in those situations - hope for the best but expect the worst. However, despite my somewhat skeptical ways, I try to live by the following mantra:
I'm a fairly massive risk taker and always have been; deciding long ago that the pain of failure is no where near as profound as the pain of staring up at your ceiling at night knowing deep down you didn't have the guts to try. That regret is something I refuse to live with, so I keep asking. Doing. I get my teeth kicked in 99 percent of the time, but when I win... I win big. Dream-come-true-big.
-Eric Schaeffer
I was in a slightly different situation and have to say because of a few risks of heartache,I won the man of my dreams.
I had recently graduated from college ("uni") and moved to Seattle a few years ago. I got a fantastic job marketing for a manufacturer.... through which I met a very charming Englishman who sold our products into the UK and Europe. We met about 2 years ago and quickly became great friends. We had an eight hour time difference and were separated by 5,000 miles - I would see him 1-2x per year for work... He convinced me to get WhatsApp and we chatted as "friends" for about a year and a half before I announced my crush on him. I actually told him about it in hopes it would make my crush disappear - because really - I didn't think it could happen. It seemed too much like a fairy tale.
Despite the distance, and the chance that we could lose our jobs that we both loved dearly, a month or so after I told him, we had to meet for work. I have never felt a more magnetic attraction and genuinely feel I found my soul mate. We started dating long distance and quickly worked out that we found in each other something neither of us had ever anticipated feeling toward anyone - let alone someone who lived so far away.
When I was in your shoes I thought it was impossible, stupid and never going to happen, but it can and will if you're really right for each other. It was hard and is a constant struggle to be away from everything you know and love - but if you liked it here for so long, it can happen if you try. Not to mention, your situation was more serious from the start than my own.
We texted constantly through whatsapp and skyped on weekends and tried to see each other every six weeks. I would add movies I loved to his Lovefilm account and I beat him on Sky Sports fantasy football in his mates' league. We did everything we could to be as involved in one anthers lives as possible. Because our employers were understanding and we already traveled that was a massive help and I am incredibly grateful for it.
We got married in September last and I now live in England with my charming English husband. If I didn't know my own situation, perhaps I would say it was silly of you to dream, but my dreams came true and no matter how hard it can be to feel foreign it's 1000% worth it. For the right person, of course. As cheesy as it sounds, I firmly believe in "when you know you know" - and you can make it work and will make it work even if that person is from another country and it seems the odds are stacked against you.
Best of luck
