If you want a great relationship, you should never play the blame game! It is human nature to shift the blame of a situation on someone else. After all, why should you be responsible? This is a selfish attitude that has no place in a loving relationship. At times you will be wrong and other times your partner will be wrong. Sometimes there is no blame at all, just a situation that needs to be worked out. By putting each other and the relationship first you will create unity and trust.
In addition to taking responsibility for your actions, you need to take and share responsibility for the everyday parts of your relationship. Share in household and yard duties, bill paying, and major decisions. For a relationship to be truly committed, you need to treat each other as equal partners. Even if one person is the primary breadwinner, you should both share in the financial decisions.
