How Can I Trust My Girlfriend?

Dear Momofuku,
I love my girlfriend and want to stay with her, but I struggle with the lack of trust between us. I want to forgive her, but how do I move on from the pain I still feel?

Dear PM,
After Momofuku Ando hit it big with instant ramen, he launched instant rice. He figured success was a foregone conclusion, given the time saving versus traditional steaming. Imagine his shock when he learned that nobody wanted it. Talking to consumers, he discovered that families trusted their mothers to make rice (mothers had been doing that reliably for centuries, after all) more than they trusted Ando's company to provide it. (It was different with instant ramen, which had no such tradition.) What we learn from this is that building trust takes time, and once established is difficult to destroy. One can guess, therefore, that trust never existed in your relationshp. You assumed it, ignored it, or moved ahead believing it would come. The instant rice debacle led Ando to abandon the product, and to coin his famous phrase, "When you enter a market do it slowly. When you withdraw, do it quickly." Whether you stay in your relationship or start a new one, take the time to see if you trust the other person -- before allowing yourself to be truly vulnerable. This can take a long time. If it never comes, you might have to "withdraw from the market." You can't will trust. Same with getting over pain, it seems.
