When divorcing a ger/ores spouse, you are being mezakeh other yidden to be able to marry and love the ger/oyes. Being mezakeh other yidden (mezakeh es ha’rabbim) is also a great mitzvah – sometimes even at the cost of one’s own mitzvah! (examples in gemarah: freeing an eved to make a minyan or for mitzva of pru u’revu).
