I’ve got into a habit of giving a woman in my hobby group a lift home. To begin with it was done as a favour but now I feel like it’s become expected and she’s started to wait around for me at the end of a session. One time when I wasn’t able to attend she messaged me on FB asking where I was! I feel like I’m being taken advantage of. For context she lives about five minutes away from me but in the opposite direction meaning I have to drive to her house and then back on myself to get home. She doesn’t drive or own a car so car sharing isn’t an option. How the hell do I get out of this without coming across as a bitch?
