No your fault was getting involved with a married (living together for 20 years) woman. You have poor personal boundaries and therefore you were unable to protect your own emotional well being. You have White Knight Syndrome by all accounts and some codependency as well if you'd keep taking someone back who continuously broke up with you just to cause drama and the excitement/relief of getting back together.
Don't disregard your own culpability. You volunteered for this over and over again. Had you a good set of personal boundaries in place, good self worth and not concerned with saving people (instead doing the work to save yourself) you would have immediately distanced yourself from an involved woman and
... saved yourself all this bullshit.
Work on YOU and stop worrying about her. If you don't do the work you need to do to respect and love yourself enough to avoid women like her, you will fall for another one just like her as sure as the sun will shine tomorrow.
