Mother in law hates me, and my baby VENTING

Not too sure how to feel when my MIL tags her son's fiancé in a post about a sale going in tomorrow for baby clothes when she's only 8 weeks along. Then here I am 24 weeks pregnant, know what we are having, and she didn't tag me or my husband. I CANT STAND THIS WOMAN. Why is she not showing excitement for my baby???? WTFFFF 😡😡😡😡
