When a relationship comes to an end, some people may use the phrase "breaking it off." However, there are several other antonyms that could be used instead of this phrase. Instead of breaking it off, one could say they are staying together, reconciling, or patching things up. Others might claim they are giving their relationship another shot or taking a break from one another. Alternatively, some people could say they are staying apart, separating, or splitting up. These are just a few examples of antonyms that you can use when talking about the end of a relationship, depending on the context and severity of the situation.
