What is commitment anyway? To me, it's deciding that this is the person that you want to be with, and giving your all- no matter what. It's knowing that the other party has the same desire to make the relationship work, and trusting that the person would put in the effort, just as you would.
And it's in that knowledge of deep commitment, that love and trust between two parties grow, and it's a constant effort in communication, listening, spending time together, and not taking each other for granted.
No relationships are easy. To think that being with "the right one" means no fights and is but a walk in the park, is foolishly naive. To think that being with "the right one" means things just fall into place and that everyone says the right thing at the right time, is imagining a sitcom or movie script.
Unfortunately, these days people give up too easily. They don't have the mettle to stick it out and make a relationship work. They choose the cowardly and easy way out, one that requires less effort.
I'm hopeful, though, that one day I'll meet someone who will decide to stick through thick and thin with me. Someone who decides that I'm worth his time and devotion, one who doesn't shirk the responsibility of being in a committed relationship. And if I don't? That's fine too. Life is too beautiful to wait for that one person. :)
