HONESTLY....it is EXTREMELY difficult and MOST marriages do NOT survive an affair. my mother is a marriage counselor now-but when i was little-she had an affair. i was so mad and for years i could not understand how my dad could just "forgive" her and "foreget" about it. the only reason their marriage survived was because : A. my mother was extremely sorry and spent a good 2-3 years just working at earning back my dad's trust-because she deeply deeply WANTED my dad; and
B. my father simply gave it to God and forgave her-because he loved her. But keep in mind, MY parents had already spent years cultivating personal relationships with Christ-on their own-so i believe that is THE ONLY reason they made it. The rest of us dont always have that to fall back on when it comes to this situation.
