I understand how you could feel abandoned. But it's her right to get pregnant when and how ever many times she wants to. Whether it was planned or not is her business. There were a handful of reasons I chose an older therapist, and this issue was one of them. While your T is on maternity leave, could you look into other therapists, and maybe try to choose one who's older, hoping that she has already raised her kids already?

I completely understand how hard this must be, again, it is something I took into consideration when looking for a T.
