What do you think?

I’ve been with bf since I was 16, I’m now 22. He’s a lovely guy and all but he is so stressed out all the time about work and other things that it affects our relationship, he can’t have a conversation maturely about an issue he just avoids talking about things or is just extremely defensive. He’s not abusive or anything but he’s lack of communication skills make it so hard for me. I don’t know what to do because I feel like I’ve tried everything and I’m still not very happy. But at the same time he’s a good person and has never done anything wrong by me.
