I sometimes read on here that therapists send texts wishing "happy birthday" or "good luck" and if I'm being perfectly honest, it would be great to receive such texts. But I understand that my T doesn't send those as it would be too close to a friendship and she is not my friend. However, checking in on me after a difficult session would be perfectly appropriate and therapeutic. But she doesn't even do that. I don't think she cares that much.
