You are right, I should ignore/avoid her as much as possible. I stopped going on Facebook for that very reason (I can only imagine what she is posting there now... puke!). I am glad I got that dreaded call over with. My DH has another sister and they both live in the same city far from us, they want us to come out for a visit but I don't think I can do it. At least I can just tell them I need to save my vacation days for IVF. We are all going on a "family trip" overseas this summer too so I will see her and the new baby in due time.
Thanks for listening and for the support, it means a lot
