Hello, I am deleting my post as I would not want my sister to somehow come upon it by accident. I'm sure if she did she would know it was about her!

Thank you everyone for the kind words and for gently allowing me to be where I no longer belong. I wish you all the best of luck!

I have a horrid SIL, and I can relate to this somewhat. It's a very different situation, but I agree that it's not very "sisterly" to plan to not say a damn thing to you about being pregnant until you mentioned it. WTH is that?! It sounds like she knew it would make you uncomfortable, and decided that that was your problem, not hers, which I think is uncool and insensitive. I agree that it was probably a difficult time for her, being newly pregnant with three little ones and a very sick father, but telling the whole world before she tells you is not okay. It sounds like it's a good time for you to think about what you want out of the relationship and what are reasonable expectations. It's been very sad for me, but I've given up on anything from my brother and SIL except for obligatory gifts and phone calls at holidays and birthdays. I wish it could be different, but that's not who they are, and it never will be. If you want to be closer with your sister, find a time to calmly discuss this with her and tell her how it made you feel. It is possible that this baby thing seems so "old hat" to her that she hardly considers it news, but that doesn't explain her decision to not mention it to you at all. I also think it's totally crazy to announce to FB that you're pregnant while your father is on his deathbed, but maybe she had her reasons.
I'm sorry for your loss and for your difficult family situation. I'm also sorry that you're now living CFNBC. I hope that you can find healing from all you've been through. ((hugs))
***Losses mentioned.*** TTC #1 since May 2012. Me: 37, OH: 41. Ectopic August 2012 => tubal damage.
There was more to this message, but I deleted it to protect my sister's feelings should she ever happen upon this post. I kept the "Thank You" because I really really mean it. You've all been very supportive.
