Should I break up with my boyfriend?

Hey,guys.
I am a girl.I have a boyfriend for merely two years.
Nowdays,I found he is not kind.He didn't care about me anymore.
When we fight with each other,he always says the reasons he have.
Never say sorry to me.Never say such as:hey baby,don't angry!
He always try to find what he have done and why he done it!!!
He always have so many reasons!!!
I couldn't bear it.Really
Why he always do that?I communicated with him yesterday.
Finally,I cried.He kept silence.
Today,he just say only a sentence:don't angry.
Who can tell me how to do it?
Should I break up with him?
I am so so so unhappy.
Need your supporting!!!
