An interesting note: my ballroom teacher recently told me that it's commonplace for teachers and students to have relationships. Seems true because there are so many rules about it in studios that it must happen often enough that studio owners need to creat policy.

To the OP: don't feel guilty about enjoying a little attention. Make a budget for it. If you can afford only one lesson per week, then so be it. Do groups for extra practice. You deserve joy as much as the next person.
