Any game or time spent has the ability to improve the relationship and create harmony. Board games that are very competitive may not achieve the desired effect but doing a puzzle together can be calming and create an atmosphere of working together. I like to suggest to my clients that are working on improving their connection that they sit together holding hands, lights off with some calm music playing. No taking, just feeling the others presence there with the soft touch of hands. These can be very emotional moments that draw couples closer. Hope this helps and give it a try.
i'm looking for games that can teach us communication skills?
Most of the board games are directed at children.
Take a look here. while most of their products are directed toward children there are a few that I see that adults can use. https://www.creativetherapystore.com/
Working with adults in marital therapy I believe one of the best ways is to get into marital counseling so that all feelings can be heard and new ways of communicating can be developed.
