You love some one but you can't get along., why is that?? Isn't that supposed to be the easiest thing to do? Shouldn't that fall into place? or is it because two people have such contradicting personalities? both stubborn perhaps? I obviously don't know the answer..because if I did, my girlfriend and I wouldn't be having these fights because of such petty and small reasons. Everything gets big and all blown up. Why is that? Ofcourse, I want this nonesense fights to stop..but how?
