How to deal with unhappy people

Melissa • Mom of 👦👦🧒🤱 & 👫💍 to the man of my dreams for 10 years now!

So I told my sister the other day I was pregnant (my 3rd) and her response was “Jesus Christ! Hopefully this is ur last kid u have enough kids for society these days!) like seriously 😒 my husband and I have been together almost 9 years married 8 and I can’t believe her response it’s so rude. Is it rude for me not to include her on updates I just feel like I don’t need those kind of people in my life even though she is my sister? Thoughts!?
