lyrics too good at goodbyes

You must think that I'm stupid You must think that I'm a fool You must think that I'm new to this But I have seen this all before I'm never gonna let you close to me Even though you mean the most to me 'Cause every time I open up, it hurts So I'm never gonna get too close to you Even when I mean the most to you In case you go and leave me in . love yourself lyrics eminem
