There are typically six stages in the development and deterioration of relationships:
1) Contact - where initial interactions and impressions are formed.
2) Involvement - the relationship is tested through increased interactions and openness.
3) Intimacy - a serious commitment is made through private and then public bonding.
4) Deterioration - dissatisfaction grows and partners withdraw from each other.
5) Repair - the relationship is analyzed and changes are made to try and reconcile.
6) Dissolution - the relationship formally ends through separation and eventually divorce.
