Thinking to much.

So here lately I have just been either sad or really upset with my boyfriend he is just always being so rude anymore. & the thing is I don't think he realizes he is being mean. But I feel like it's starting to make me lose feelings towards him but then within the hour we are laughing and smiling and just having a good time. So I don't know what to think I don't want to hurt him but I just don't know if I'm happy anymore. Anyone else ever felt this way?? Or have any advice I'm in need of it.
