Day 6 of no contact

He emailed today..."How are you?"  I haven't responded now to 3 emails from him.  He's going to have to get the hint and realize something is wrong.
I'm thinking about phasing out....I know I can't do cold turkey.  Maybe I'll go from one week not seeing him, to 2 weeks, to 3 weeks, and on and on until I'm done.  
In the meantime I'm taking care of me.  Working out, I'm down 22 lbs.  I feel good.  A few more pounds and I'll be ready to start meeting someone new.
I'm resisting the urge to email him back.  Maybe tomorrow when he emails again- he's got to know something is up.
