Who do you think is right, me or him??

My boyfriend is always calling me names such as Fatty, Fat Cow, and stuff like that. That is how he shows his love, according to him. That is his own way on being cute. The weird thing about it is that im no where near fat. Im 5' 4'' and i weigh 120. Then when it comes to argueing he starts cursing real bad when all i want is for him to understand my perspective. What Should I do? I love him to much to let him go.
