Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh. 
In principle, if the husband utters a statement which has dual or multiple meanings and some of the meanings could imply divorce, then divorce would take place only if the husband intended divorce. In the enquired situation, the husband stated, “their relationship will be over”. The husband did not intend divorce from this statement; hence, this will not constitute a divorce.[1]
