This weekend my whole family (Mom, Dad, brother, sister and her husband, me and my husband) is staying at my parents cabin friday to sunday. 2 weeks ago when we stayed at the cabin me and my pregnant sister got into it.

Ever since she has been pregnant I have been supportive and been interested in everything. It has been hard for me because I so badly want to be pregnant now. This list is some of the things that have gone on since she has been pregnant.
*She told me I only talk to her now that she is pregnant
*She said she doesn't want me to throw the baby shower because I will make it all about me.
*She bit my head off when I asked how far along she is and how she is feeling. (Seriously, even my poor mom backed away from her)
*She makes me come over like every other week to paint something new. I really don't mind helping but she doesn't give me a thanks or anything.
*I asked if she was eating deli meat and she blew up at me again, telling me never to give her pregnancy advice because I have never been pregnant. (I have been pregnant twice, she didn't know)
*Called me an idiot for wanting to switch to a Reproductive specialist from the OB doc we both share.

Anyways that is just a short list of what has gone on between us. And I am not perfect, but I walk with tip toes around her and she still blows up. I do not know what to do anymore, our relationship has always been tense and now I feel like it is over. Even my mom is siding with me on this one, and my dad and brother work with her and think she is unbearable. She has like 15 weeks left of the pregnancy I think. HELP!
