No, it wouldn't bother me. I'm young(ish) and infinitely single, my T is older and married. I actually met her hubby once when there was a minor mix up with my appointment, he seemed nice. I think it's good thing for a T to evidently have some success with relationships? The way I see it, the more areas in which my T has life experience, the more reassured I am that she's 'qualified' to help me function in my own life and situations... Maybe I'll actually need dating/relationship advice at some point!
