If she previously moved to Tulsa without objection from dad, he's going to have a hard time explaining why he NOW has a problem with it.If she moves, it will be further away. Here's the moves.
1. Oklahoma City to Tulsa
2. Tulsa to Stillwater (closer to us)
3. Stillwater BACK to Tulsa
We live in Oklahoma City.
BTW, she pretty much can't get a cheaper apartment than what she is already in. The one she is in is all bills paid.
