It's not that you don't love and adore your precious one with every ounce of your being. It's just that if you have to listen to that superior tone of voice for one more second, you're going to put your fist through a wall. Your matchups have a way of turning into mismatches -- with your expansive, confident partner running roughshod over playful little you.
It's possible that your lover is significantly older than you, or in some way more worldly -- better educated? more advanced careerwise? Certainly you feel at a disadvantage next to your sweetie, more like a student listening to a teacher's discourse, or a kid being lectured by a parent than a true partner. On the other hand, there is a lot your lover can teach you if you're able to walk the fine line between willing acolyte and bullied wretch. Demand respect from your partner. A polite tone of voice is a must, and snide remarks won't be tolerated by you. Once you begin standing up for yourself, the balance of power in the relationship will shift, and you can both start enjoying the pleasant buzz of your stimulating love relationship.
