Love is a willing committment.
A mother changes her baby's diaper, not because it makes her feel good, but because she has committed herself to her baby.
Parents work and pay bills for children not because they feel like getting up early every morning, but rather because they have committed themselves to their children.
Children hurt their parents feelings, yet the parents continue to look out for thier best interest. They don't do that because they feel like it - they are deeply hurt at the time. They do it because they have committed themselves to their kids.
Two people form a team, look out for each other, provide for each other, defend each other, and build a life together. Along the way, I can guarantee there are days when each doesn't feel like continuing. There are days when each is bored, stressed, sad, and sometimes even lonely. They continue doing what they do because they have committed to each other. In that committment, there are the rewarding moments that make it all worth while in the big scheme.
People make the mistake of thinking love is something that makes them feel good, or something for them. They look for someone to make them feel good instead of looking for someone to love. They want someone to love them, but are not willing to make the committment themselves.
(how's that? :) ).
