Perhaps you are entering a new phase of life, such as new addition to family, relocation, loss of independence, communication challenges. While some of those events can be exciting, change can be daunting and impact couples/marriages in various ways. Whatever changes you are going through, it could be that you both are feeling uncertain about steps to move forward.
Therapist can provide a safe space where you can explore your problems and their solutions so you can better face transitions in your life.
Changes can be hard to accept and difficult to adjust to, but that does not mean they are entirely bad. They give you an opportunity to set new goals and try new things. Your life may be going in a different direction than you expected right now, but you can still find happiness in your new situation.
