Relationships fall and whither because eventually someone stops trying and it doesn't feel the same. The first couple of months or even years it may be the best thing you ever wished for, but eventually someone loses feelings, gets to busy, or doesn't even bother to try. You know why? Because they're comfortable. The beginning is all about the chase. Can you keep up? If you can then you'll get the hang of it and then you won’t want to try anymore. You aren't afraid to lose them because they're yours. Arguing leads to fighting and it just gets worse from there. It all flashes by so fast. So, cherish what you have.
