You and your partner are now ready to blend personalities and learn to live together in true partnership. Areas of friction indicate problems that need to be solved. You can only change yourself in a relationship. Changing your partner must never be the goal. Healing your past, building self-esteem, dealing with feelings, and speaking from your own experience will eventually impact your partner, creating new patterns of relating.
Conflict is inevitable.
Whenever two people get together, eventually some of the belief systems and personal habits of one will annoy the other, regardless of how much love there is. In healthy relationships couples learn how to resolve conflict. Confrontation is normal and healthy. The sooner you bring up issues when you feel hurt, taken advantage of, irritated, misunderstood, or ignored, the better for the relationship. Suppressing them keeps you a victim and only leads to hostility and feelings of separateness.
