If you don't know me by now

All the things that we've been through you should understand me like I understand you .. Just trust in me like I trust in you as long as we've been together it should be so easy to do just get yourself together or we might as well say goodbye,what good is a love affair when you can't see eye to eye? But we can't tell the future no but that's just the beauty of the world we know. Don't know what tomorrow brings but I'm still hoping that you are the one for me,and what if I had you, and what if you had me and whats the reason we can't fall in love?
