He's a Lover...Not a Husband

Usher says that he struggles with being monogamous because he’s not good at being in love. He told Cosmo, “I'm good at making love, but I'm not good at being in love. It's a conscious decision every day to love the person you're with." Source
Is this his way of slowly easing out of his marriage? Did he finally stumble upon her nutsack and now realizes it’s time to move on?
