Awful, am I?

He has knocked me off again.
It started when I changed my profile on twitter then he read it. He asked why did I changed and erased his name. I answered honestly that I was bored with the old one, didn't mean to erase his name or else. He turned mad at my 'bored' word and started to say a lot of bad-think about me. Again he misunderstood of what I did. I swear I never think about forgetting him or hide him from my friends. I do proud of him and want my friends know I have a man. I told to him but he didn't believe me.
He opened up the past moment, when I forgot about his birthday and it totally made me feel awful. I remember the feeling how he was disappointed when I said the wrong date of his birthday.
He sent me a message, he said he doesn't need any romance thing from me but honesty relationship. That made me feel worst than ever. I really thought I don't deserve to have a nice guy like him. If he could said that it meant I do nothing for our relationship, or he couldn't see my effort to keep this relationship. So what for I? He gave me everything but I didn't give him any, even couldn't comfort him.
If I could express how guilty I feel, and turned back the time not for me to keep the profile on my tweeter, but for me to not in relationship with him so I would never hurt him and disappoint him this deep.
