Confused....

Why do I get so dang confused every time this mofo comes back into my life?!?! Its like so many emotions and feelings that I can't make out what I really think and feel. Is that good or bad? And why is it always such inopportune times that he walks back into my life?!? In fact, why does he walk back into my life at all? Can't he just walk out and not turn back? Why do we keep going down this road? A little over two years of this...and I don't know what to think anymore. Argh....
