I’ve had three T’s go on maternity leave: the fist two never came back and the third, my last T came back only to get pregnant again. She made a whole lot of false promises the second time which have resulted in me deciding to no longer see her (I’ve posted about this already so I won’t bore you with the details).
My point is I get how painful this is and I think Ts need more training on how to handle these situations rather than make promises they can’t keep. I hope you’re able to work through all your feelings before she leaves and that she stays true to her word.
