Small chunks from brush in paint
Sounds like you have to redo the whole thing.

You are a brave soul for admitting what you did.  I think I would have just redone it before anyone found out, especially my wife.

You might try just getting a new brush and doing your second coat.  It could cover up the chunks, or you could end up with two coats to sand back off.  If the latter, I would keep it silent.
