I’m getting really good at writing about my boyfriend and I don’t know how

I have a boyfriend and I am really good at writing about it. We’re in the US and he’s from a small country in Africa. He’s pretty good at writing about stuff that’s pretty important to him. Things like: where he’s from, how he lives, where he loves to eat, how he feels about things. Stuff that I’ve never felt like I could share in a way that’s safe. I’m pretty proud of how much he’s improving and I’m happy that he’s getting better at writing about my problems. I don’t know how to be proud of him. I know he’s got a way to go and that’s a huge compliment. But it’s hard to be proud of someone when their best friend is getting better at writing about them. I hope this doesn’t turn into something worse.
