Why it's always me?

I been through relations, have dum every crazy thing except , thinking to share "that" fk-movement with the "one" I will spend my life with. However, lately I have started feeling guilty for some reason; I don't know. Is it mean that now it is the time for me to step up and take what already mine or hold myself for the "one"? I need ur thoughts about this, kindly guide me...
