It's not fair

Shelby • Two Valentine`s babies TTC their own little love child. <3
My sister's sister in law and brother in law (her hubby's brother and his wife wife) just announced their pregnancy on FB and I just got SUPER emotional SUPER fast. Instantly felt actual heart pain and tears poured out immediately. Every time I pass it on my feed, I get an instant (and real) pang in my heart. I would be SO happy for them except: they have adamantly said over and over again that they don't want kids. I know things change and they don't have to announce to everyone that they changed their minds, but it just hurts me so bad.  And they got my sister a "proud aunty" pin and she's all excited and posting pictures wearing it, and I feel bad being upset at that, but it just doesn't feel fair. I know it's petty and selfish, but my emotions don't care. Anyways, thanks for letting me vent. Tried crying to hubby about it and he just brushed it off. I am so sad, but I feel like a serious jerk for being sad about it.
