I am a HOT TEMPERED !

I cant believe that my hot tempered will be getting worst. Actually I'm not like that, i use to be patient and stay cool what ever it is not just scream to her face and do things that not healthy. i don't know why i have to that with Raine. This habit are not healthy to my self or our relationship, hopefully i will cool down and speak politely to her. Having in this situation give me awareness to myself and I'm afraid that she will hate me and would not be able stay longer. I hope i have a solution for this matter. I don't know how to reduce this anger from myself. maybe because shes the one that i very comfortable with and i trust her so that i will do anything to her. My bad i have to apologize but i don't know if she will forgive me now ?? :(
