Life does that sometimes. Sometimes you find somebody who's completely perfect on the outside, but you find their true personality later on. Sometimes the opposite happens. Personally, I've never been in a relationship, but I've felt that way too, I mean moving around doesn't give you lots of relationships to hold on to, and things fade away. The only thing we can really do is try to hold on to those who are dearest to us and try not to hurt them, to consider their feelings, and to hold our own.
