No. The right one is fall out. Though we are very familier wid 'fall apart'. But it doesn't make the right sense here, fall apart means to have some distance between two (physically). But here the sense is of "not being united" i.e. to have distance mentally.

FALL OUT means quarrel. It is opposite/antonym of harmony. If it had been unity/together instead of harmony, apart would have been right.
