Fighting all the time

My boyfriend & I have been going out for 6 months now. He is a nice guy and all but we seem to argue most of the time. He treats me very well. Loves me very much too but we just cannot see eye to eye on most things. On & off he will threaten to break up when we argue. I do not know whether I love him very much or just oblige him because he is such a sweetheart.

Should I really let it go once and for all? Do all these arguments shows that we are not right for each other?
