Because a female will not lock or show interest all of the sudden does not mean she is done.
Not uncommon for them not to lock for a while and than start locking again later on.
Also remember because you do not see anything and they are each on one end of the enclosure does not mean that nothings happened.
Has you female shown any signs such as glowing, building? Did you witness an ovulation.
Unless you have witness an ovulation I would recommend you to keep pairing.
