As a family law practitioner I can tell you that many never overcome their problems and it has provided me a handsome living for decades.
That said, I try to discourage divorce when potential clients come to see me. One of the first things I tell them is to ‘uninvolve’ your families in your situation. The couple’s business, strife, etc. is not the business of siblings, parents, grandparents, aunts, uncles, cousins et. al. The more others know and interfere, the less likely that harmony can be achieved.
Discussions with a competent psychologist may be helpful, BUT not therapists advertising themselves as marriage counselors. Marriage counselors often suggest ending the marriage, not fixing the problems each party has that may be contributing to the disharmony.
