Opinion needed!

So my boyfriend has a child already. We’ve been together for two years and have a house together. Ever since we first started dating he said he doesn’t want anymore children due to issues with his current child. I’m due to have my birth control removed at the end of next month and he keeps making little sly baby comments. For example: we went past my GYN Office last night and he just looked over and said “your not going to convince me out of getting a new one out in” but then he makes comments about us having a child together. Do you think he’s thinking about it or he’s dead set on not having anymore? He gives off the impression that he doesn’t want anymore, but when we’re alone we talk about it sometimes. Any and all opinions are appreciated!
