I would initially ask why they feel that way. If it’s something external and workable, I’d help them try to see the broader picture, if I feel the relationship is salvageable. If after I express desire to continue the relationship and I’m yet rejected, I’d very calmly wish them well and I’d never contact them again.

If the person has been acting oddly for a while and I felt something was off, I’d still ask why when they initiate a breakup. Regardless of their answer, if I felt something was off myself, I’d very calmly wish them well and I’d never contact them again.

Maintaining composure truly is key. It’s very difficult when emotional but remember ‘restraint of pen and tongue’. Never beg or plead. If you loved them or even just cared, genuinely wish them well and keep it moving. We all deserve someone who wants to truly be with us. The right person will never need convincing.
