I started the 25 day challenge in mid August.  Me and ex were not speaking at all.  I did the no contact and followed all the rules.  Now we are friendly and texting.  He has warmed up some in his conversation with me.  Last week he sent congratulatory flowers to my new business.  He has not made any attempt to see me or speak to me on the phone.  I am wondering if doing the 25 day challenge again will help further progress or if I should just keep doing what Im doing and that is focus on myself and stay positive.
