i am a mess

why i always screw up on relationship?
why is it so hard for me to admit my mistake,,
and instead of saying sorry here i am crying like a fool..
As always now my dark thoughts r taking its part (again!)
now I'm thinking..it might be better for him without me..
I just want to make him happy..
and if with me he only feels anger and pain..
maybe it's time for me to move aside..
