So lost

I don't understand how my boyfriend can lie about lying??? The crap that is even being lied about is so little in the big scheme of things. It is crazy how he would rather fight and make me out to be crazy or make me out to be deaf and blind, rather than just to own up to his white lie. I am left with no other option but to scream, yell and act crazy because he just doesnt get it. I spent the entire day today alone, hurt, broken and feeling really low about my life all because he cant admit he lied. I feel so lost.
