Frustrated 😤🙄

When my boyfriend and I talk about things I feel like it doesn’t really go anywhere. Like he may only say a little bit of something or say something that isn’t understandable or just expect me to get what he means. That or say “I’ve been saying this” when in reality he hasn’t been saying things in the particular way I guess for me to understand. It makes me so frustrated to the point where I rather not talk about things at all . Just talk about basic whatever stuff.. not the deep things . What’s worse is I’m having his baby ... how can things be like this now and there’s a child on the way? We should be doing better with communication but we’re not.
