Disciple or Doormat?

This is an entry I had started a couple of months ago and have been thinking about it from time to time. It was something I was rolling around in my mind after someone that I had counted on had bailed on me. And after that I started to really wrestle with the fine line between the two.

What is the difference between putting yourself out there for someone and being used and walked on like a doormat? I do understand that to be Christlike IS to be all things to all people that we might win some but where is the line? My reaction after this particular time was hurt and disappointment more than anything.
