Was this rude, or am I being ridiculous?

I found out today that a very close family member is pregnant. Hooray for her, and all that, but… she knows how desperately I want to have another baby. She looked at me and said, “I bet you’re jealous, aren’t you? Ha!” And she said it with a tacky, smug little grin.

It felt like she’d slapped me and I cried all the way home. Am I just being completely ridiculous, or does that seem like a rude thing for her to do, since she knows how I feel?
