You can't. Any human can empathize, some do it better than others. If you are hurting they will sense of feel it. They have to mourn with you and it really can't be stopped.
Ideally, you are strong enough as a couple to support each other and talk through it.
Breaking up sucks horribly...best of luck with the healing.
