Parenting decision. What would you do?

Sooo I have a friend in need of advice. Idk what to tell her. She was dating this guy who is a teacher. The breakup was not very nice but it is what it is. Over and done.

The issue is, She’s changing her sons school and had been planning on sending him to the same school he teaches at (before he even walked into the picture) if things didn’t work out at his current school. She knows she shouldn’t base that situation on making a decision in regards to her child’s education (which is far more important than anything) but she doesn’t want to look like She’s following the man, lol. All options are being explored but the area we live in is so limited in good & affordable schools. 😩😩 what do you ladies think about this situation & if this were you.
