I know how that can be. when I was over here (england) i thought constantly about the girl back home and it was rough. But I had to make a decision and was not ready to say that it was true love, although love it was. I still do miss her to the day, but i have moved on adn wouldn't look back on it twice now
The only prob is my girl leaves for 5 mo's beg. of jan...same thing ALL over again (jsut the other way round ).. I think it's sounded as if you really do love B, and like it or not a decision does//will have to be made (the GREATEST problem i had, and don't want to repeat)
