How do I reconcile this with U=kqq/r ?
Isn't r getting smaller as they approach and bond? Then U is getting larger.

Since we are talking about attractive forces here one of the `q's is positive and the other negative so as r gets smaller U gets more negative, i.e., its value goes down.

Good Luck,
