Unrealistic vs Realistic Expectations?

I was in your situation sometimes ago.She always thought something id going wrong with our relation.I am 5 inches taller than her,still she thought am not good enough,She thought i am changed with time,she thought i fight with her everyday(the fact is she is the one who does it,and i bear everything).after all this, i just let her be alone,i mean sometimes distance helps us to realise someone's importance.Just let her miss you and see what happens.Mind 'If someone is not yours today,wasn't yours yesterdy 2
