I agree on waiting at least. But if it ok id like to give my 2 cents from a girls perspective and one who's experienced a lot of life as well as this exact scenario. I can almost guarantee she remembers what Iceland means to you. Typically girls don't forget that kind of knowledge that shared from someone they are really close to. Also I can almost guarantee she already knows that you still have strong feelings for her still. I guess it boils down to how much of a friend she is to you. It is so rare that there aren't deep feelings that develop on one party or both when in a close friendship with opposite sex. There is a reason you were drawn to her as a friend, qualities you appreciated, things you had in common so it seems only natural that as the friendships develops and gets closer all those things that drew you to her would increase and even more are discovered making the connection stronger and more emotionally binding. I feel its the natural process of things. I was mostly friends with only guys in high school. I hated girl drama and guys weren't catty and etc! well a couple very close close guy friends I would have described my feelings for exactly as you did of your interest just grew and grew as our friendship did. Then we decided to date. when it didn't work out and one said lets just go back to being friends that was an impossibility after crossing over the line. I'm sure some are able but it is so rare to ever be able to go back as your were in closeness as friends. So I ultimately lost these amazing friends! So the question becomes is it worth the risk? the fact that you were able to experience your first time together and go back to just a friendship is pretty amazing but I think you said that things were different after. I really hope I didn't offend you in any way sharing this but I've lost a couple really great guys due to taking the risk. it ended up not worth it cuz I lost them entirely.So give a lot of thought on your decision. sorry to go on and on!!!
