Do i have a right to be mad?

So my sister and i have always been super close. We are 10 months apart. But we are those kind of sisters where we are so close we feel like we can feel when the other us going through something. Our periods are even synced together. We get freaking cramps or stomach aches together.

The only difference between my sister and i is i have always wanted to get married and have kids. And she has always wanted a baby in general. Honestly shes been having sex trying to get pregnant since 10th grade but has never gotten pregnant. I miscarried at 9 weeks in september of 2018. And what infuriated me was when i told her instead of comforting me and being there it was “well i think i did too because im bleeding heavily.”..... she never took a pregnancy test. She never had anything confirmed. I did.

So i texted her recently because out of nowhere i realized....that day i texted her was what was suppose to be my due date. And once again instead of being there for me i got “i know sissy i feel the same way because mine is coming up too.”

What do i do? How am i suppose to react? What am i suppose to say? I love her but she wants a baby so bad she imagines it in her head. She wants a baby so bad her “husband” had a kid with his ex that he signed over rights to because he didnt want her but she still says “thats my daughter im a step mom blah blah blah.” Am i wrong for feeling how i’m feeling?”
