I'm in an LDR, and have been for nearly 2 years now. My boyfriend lives in the UK, and I live in the US. There are some days that the distance is killer for me, and there are other times that it's not too bad.
We visit when we can, but it still seems to be about 5-6 months in between visits. Which sucks. A lot. However, it does seem to make our time together just that much more amazing.
I am looking forward to the day that we can be together full time, but I'm not really in a rush to get there. Which is a good thing, really, because the immigration rules in the UK are going to make it REALLY tough for us to qualify for a fiance/spouse visa. I am thinking about going there for a student visa (I've been wanting to get either a second bachelors degree, or a masters degree), which would enable me to stay in the country for an extended period of time, and to help us test the waters of being together on a long term basis.
