Does passion end when commitment begins?

Got this question from the movie trailer 'When love begins' starred by Aga Muhlach and Anne Curtis. It made me ask myself the same question. Does passion really end when commitment begins? After tons of evaluation, yes, i think it's true. I've been married for almost 8 years now. After the honeymoon stage ends, disillusionment begins. This is the time when you discover all the not-so-good things about your partner. This is also the time when responsibilities come in. Issues like money usually start at this stage too. With all of these things happening at the same time, passion could really be affected. Both need to work hard to stay in love. In this time, your friendship with your partner will be put to test. This so-called friendship will hold you both together. That's why we all said that there has to be friendship in every love relationship. It will served as a foundation to a solid relationship with your partner. Sometimes, after years in marriage, love will not be enough. This will then be your weapon on this hard times. Without friendship, love might not survive. The components of this friendship, trust and respect for each other, will strengthen the bond. So don't fret. Passion might be diminished, but a deeper connection through friendship will grow, and that's the most stable relationship in the world.
