Really?!

So my husband and I have had our baby boys name picked out since 18 weeks pregnant. When we found out the gender at 21 weeks I of course posted about it and have continuously posted his name when giving updates. Well the other day I get on my Facebook and a girl I went to high school with who has liked all of my posts has now decided at 16 weeks she's gonna name her baby the EXACT same name! Like middle and first the same as what I have been posting. Maybe I'm being crazy but now my husband wants to change the spelling of his name because of her but I absolutely hate the other spellings. I just don't understand why you would steal someone else's name knowing our kids are gonna be going to the same school
