You feel accepted when your mate is able to understand your feelings, is able to "walk a mile in your moccasins" and resists judging you. Acceptance is not the same as agreeing with you, just that your partner makes the effort to understand you and values your right to your views, feelings and desires.
The final element is a shared responsibility for relationship problems. Couples typically come into my office with the hope that I will appreciate their suffering in their marriage and that I will convince their partner to change. This approach never leads to change, only a pattern of defensiveness. Couples must find mutual solutions to problems. The only solutions that work are ones in which each partner is able to see a role for themselves in bringing about change.
Take a moment to assess whether you offer these four elements to your partner and whether you, in turn, receive them. If not, take time to have discussions with your partner that focus on giving and receiving these elements. You will find that the relationship will become more enjoyable and that you will find each other more attractive.
