The concept of LOYALTY run amuck?

So I'm the loyal sort. I go through the same routine and see the same few people on a regular basis. I sponsor the same vendors, work with the same team, support the same causes. It's a matter of LOYALTY to me. The problem is that everyone knows this about me and it tends to elicit abusive/neglectful behavior from people (including a few work colleagues, local vendors, close friends, and, of course the physically and verbally abusive ex-husband). Really extreme stuff that I won't bore you all with here.

Has anyone else here -- guys or girls, please! -- worked past this sort of issue?

How to I break the cycle? I want to stop being the doormat!
