Hey sunrise,
I also tend not to be drawn toward people who are "taken" so that's helpful. My therapist is also married and mentioned that he's been married 26 years (or something like that). He sometimes mentions things about his relationship with his wife (not very detailed of course like most therapists, but he gives me an idea of what maintaining a relationship is like). I like knowing that he has a healthy relationship. It makes me more sure that he knows what he's talking about. I hope I can have a long healthy relationship one day too. I would like to be happy. And of course I'd love for him to see me happy too. I'm sure he would like it.
