Conflict is inevitable in any relationship. After all, there are two people involved, and both have feelings and personalities. But when arguments become bitter and divisive, it can threaten the love and mutual appreciation that brought you together. Tension replaces affection, and cold silences mute communication and laughter. Married or not, couples in this situation feel so deeply frustrated that they're often ready to throw in the towel.
Relationship counseling can help, if both of you want to stay together and work it through. It's just easier to sort through the issues when you have a skilled facilitator to help you communicate. Often the outcome is renewal of love and commitment, which is always the goal. But sometimes counseling simply helps two people recognize the time for change, and end the pain. When children are involved, their emotions and security need to be thoughtfully considered as well, so everyone’s needs are fully appreciated and taken into account.
Virtually all psychotherapists provide relationship counseling, of course. However, it's important for the two of you to find the person who makes both of you feel comfortable and confident. Too often couples choose a therapist without much thought, perhaps one of them choosing and the other "going along." My advice: if you're considering couple counseling, take a look at Choosing A Therapist before you move ahead. Then, make sure you both feel good about who you’ve selected, or ask for a no-cost, no-commitment “test drive” with 2 or 3 therapists before making your mutual decision.
