be (not) on speaking terms
To have an amicable, although perhaps guarded or superficial, relationship with someone. This phrase is often used in the negative to show that two people are estranged. It took a long time, but my ex-husband and I are finally on speaking terms these days. After that argument last night, I'm not on speaking terms with Stephanie. I don't know Kyle that well, but we're on speaking terms, and he seems nice enough.
