bad person

Yesterday I learned that I am a very bad person, a person one cannot be in relationship with. I show when I am unhappy, when things dont go my way and doing that I hurt people. My boyfriend told me yesterday so much...I was angry when he was 15 min late, when he didnt go for a dinner with me, when I told him I dont want his friends to come over (it was a middle of the week, I was tired and I had to get up at 6am, They came over at 9 with two bottles of wine - would anyone else be mad?). The good things I reminded him: a fluke. ehhhh....should I stop caring for what I want, what I need. Will that make me a better person, a person who would never have to hear how bad she is? Any thoughts? I am confused.
