Can I start counselling on my own if my spouse is not yet ready to join?

Yes, counselling on your own is still beneficial and can be a good start even if your spouse has not yet joined. You can learn healthier ways to communicate, manage your emotions, and understand your part in the cycle of arguments. Changes in yourself often change the atmosphere at home and sometimes encourage your spouse to open up later too. Do not make the sessions a place to collect arguments to blame your spouse, but a place to improve yourself. Share what you learn positively so they can see the benefit. Start without waiting for them to be ready; your effort still has value. See counselling.
