It's simple. The only thing that's indicative of the true value of your relationship and if it's worth investing time into is that line from the wows "in sickness and in health". If your partner isn't literally your lifeboat you'll never know if you made the wrong choice. My parents passed this test when my mom was diagnosed with ALS and could no longer walk on her own. My dad could have cheated and she'd never find out. He didn't. He could have left us; he didn't. So take care of yourself and stay healthy. Otherwise you might be in for an uneasy surprise.
