Rob makes an excellent point. I used to teach SCUBA and I'd always split up spouses untill the end of the class. I learned this rule from a dance instructor and it served me well. One person would always end up depending on the other at the least and the extra baggage of the relationship would carry over to the class. You could tell her to level the wings and in her mind she might be thinking he really doesn't love me. With an instructor with no prior history, level the wings means level the wings.

You'll both enjoy your time at the field a lot more with a flying partner than with a student/ teacher relationship forever.
