Relationships can be so confusing sometimes. It is easier to tell people how you feel if you approach the conversation warmly. Something like this- I love you, but you are hurting me because you get so angry all the time. I am willing to change to make you happy, but you need to be nicer to me so I can work on myself. If that doesn't work, maybe hes not right for you...I know you may think he is the only thing that is making you happy, but the subject of this is so upset. Maybe happy is what you felt at the beginning of the relationship, but look at what he is doing to you. Consider your relationship, and think about what will be best for your future. Good luck!
