Boyfriend sucks at communication, how to fix it?

My boyfriend of two years sucks at communication. Whenever I try to talk to him about something like boundaries, feelings, arguments, etc. I always feel frustrated. Here's what he does

-answer my question with a question repeating what I said Example: how would you feel if ...? Him: well how would you feel?

He's been doing that lately and never used to.

-he would change the subject

-when I asked for his input or why he feels a certain way about things it's always "I don't know" and I'm like really? he really doesn't know or if he's just lazy to think of a reason

Ugh! I was hoping talking would make me feel better but it just made me frustrated
