Confused...

Me and my boyfriend been together for 3 years, had a baby 6 months ago. We’ve been through a lot together and matured a lot. Something that makes us argue is his lack of communication. I feel like he doesn’t understand how important it is for us to have communication for us. If we get into a disagreement, majority of the time he gets frustrated or stays silent.. he is dyslexic and has always been and also he’s been like this throughout our whole relationship and this is something that he acknowledges he wants to fix. I’m really impatient and I tend to get frustrated at him for no communication or not knowing how to move forward because I don’t know how he’s feeling. Advice ladies? What would you do or think? Thanks in advance💗
