It appears from the question that the husband called the family members and gave one talaq; this was one raj’i talaq (revocable) which took place. The husband can take her back if three months did not pass after this talaq. But if the iddah of the woman was over after this talaq, then she got separated (bayina). Now, if they want to live together they can marry again with a fresh nikah and live as husband and wife. The rulings so if it is proved that the husband did not give three talaqs.
Allah knows Best!
