Oftentimes, your first relationship, will not be your last. It may sound bitter , but it's true. I too, dreamt of having just one perfect relationship and that's it, but it didn't happen.
Relationships have ups and downs. There will always be lover's quarrel. One point you're exchanging sweet messages, the next time you'll throw hateful words against each other. But after the fight, you'll reconcile and act like nothing happened. Silly isn't it? That's a normal thing about commitments. Arguments within the relationship is just to spice things up, and to make the bond a bit stronger.
Some relationships lasts long, but other's are just short-lived. Few will have you march along the church isle, but there are some that wouldn't make it that far. Yes, not all relationships could stand the test of time.
After the break up, ex couples would sometimes decide to just go back as friends. On the other hand, there are also those kind of ex lovers who become mortal enemies in the end. Can you guess what their favorite game is? The "Blame Game". Pointing fingers against each other, and coming up with a long list of mistakes both party committed. Debating on who is to blame and who is the reason for the tragic end of the relationship. Both are trying to gain other people's sympathy.
Truth is, relationship is never black and white. It's not like one is guilty and the other one is innocent, or one is to blame and the other one is the righteous. It's never like that. Both party commits mistakes, and it doesn't matter who commits the most mistakes. For as long as the two of you exerted an effort to at least save the relationship--if it's worth saving. But if it didn't work, in spite all the possible solutions made, then it was never meant.
On the positive note, after every failure relationship, is a lesson learned.
