M.S.
I know what you are going through. I went through a similar situation with my fiance. We were best friends for 5 years before we started dating. We dated got VERY serious and he ended it, but we still hung out every day among other things. I moved away for 3 months and we talked almost everyday. i had to move back home he offered me his place though he said he didn't want to get back together. We got intimate sometimes but he still didn't want to be back together. We lived together for a year and half before he started calling me his girlfriend again and began talking about marraige. We always knew we would be together but he needed time. IF you know deep down that you will be together again than go on this vacation. Sometimes what people need is time. I will tell you though that it was the hardest thing i ever had to do letting him do his thing and still being as close as we were. It was worth it in the end. How do you feel deep down? Don't worry about how weird the situation is to other people. It is ultimately up to you to choose whether this is right for YOU.
