sharing with family

SA

I thought it would bring great joy to tell my sister I was pregnant and all the response I got was "oh great you'll be a cow at my wedding" mind you her wedding is sept 29 and I'll only be 14 weeks. she then got pissed as hell because I said I was going to announce my pregnancy at 12 weeks and shes pissed bc that would be before her wedding... as if that even matters. I dont even feel like including her in anything else in my pregnancy if that is how she is going to act... anyone else deal with this with family members? when I told my parents they were excited but she was around and she just acted like she hated me and my husband for getting pregnant before her wedding like we have to plan our life around her... wtf!!
