He acts different

So my boyfriend lately has been acting different. I constantly feel like I am grasping at straws. I say I miss him and his kisses.. he says something else completely different (through text) I finally caved and told him that he has been acting different and that he needs to be honest with me otherwise it’s over. Because when I know something is off, something is off. I am always right with that.

We have only been dating a month. So it’s a little easy. I am crying but it’s only because he’s a waste of time apparently. But wtf? How all of a sudden do you lose interest in someone so fast? I’m so over it.
