Need advice

I’m in a relationship I’m 22 and he’s is 34. I know thats a big age difference but I love him and he loves me. he is honestly the most sweet and supper honest and supportive guy ever but he does get down on himself and does have bad depression also anxiety. he was in the military for 8 years and before that he never really had any buddy he could count on or family and growing up was really rough and hard on him. Also he has a lot going on right now and I have no idea how to help him. I just want him to be happy. Should I have said something different? Or does any one have any advice on how I could be more supportive? Here’s the conversation we just had. I feel like I should have just listened Instead And I feel like I made it about me instead. Did I do that? What should I do?
