You’re having trouble communicating with each other
Usually, the first sign of problems in a relationship is lack of good communication. Being able to talk through an issue without it turning into a war of words can ease the stress in your relationship. Therapy and counseling are all about communication. A good therapist can help you communicate better. An even better therapist can help you learn the tools to do it on your own after you’ve left counseling.
You’ve ever mentioned the D-word (divorce) to each other
Once you bring up divorce, it’s akin to holding it over your partner’s head like an anvil waiting to drop. At this juncture, help from a couples’ counselor can be crucial to getting back on track. Contemplating divorce means that one of you already has a foot out the door, and being in a committed relationship works only when both of you are all in.
