i don't think that it was the thought that nobody expected you to be capable of such feelings.....usually there is a buildup of things being said & feelings that exchange before getting to that point in a relationship.....& if she never felt or heard some of those clues before you came out with the "i love you" it would naturally come as a shock.....just a little insight that might give a bit of understanding. Relationships are difficult enough no matter what......but communication is such an important part of relationships & when communication is difficult, it makes it that much more difficult to get all the pieces of the puzzle to come together
