@Eorl,
Yes, you are almost half right.
Love is not self seeking
Good Quote:
Love is patient, love is kind and is not jealous;
love does not brag and is not arrogant, does not act unbecomingly;
it does not seek its own, is not provoked, does not take into account a wrong suffered,
does not rejoice in unrighteousness, but rejoices with the truth;
bears all things, believes all things, hopes all things, endures all things.
Love never fails...But now faith, hope, love, abide these three; but the greatest of these is love.
1 Corinthians 13:4-7,13
As a wife, if you're able to achieve just 10% of the definition of Love above- first line, I think your husband will get rid of the home wrecker himself.
