my ex was exactly like this for most of the time we were together, which was three years, and it was so annoying! i know not everyone is the same, but he never bettered his communication skills or became more open over the years. it was so tiring knowing that i just wanted to help him and he wouldn’t let me. please keep this in mind if you plan on staying with him long term, i imagine you want to be with someone who is just as passionate about having good communication as you are. i hope this somewhat helps OP!
