Liz, I had a similar bout of super low self esteem a few months ago, and it lasted for about 5-6 weeks. Fortunately, I was able to explain to my gentleman friend that it had absolutely nothing to do with anything he had said or done. Mine was less about comparing myself to women from his past, and more about my struggles with worrying that mistakes and experiences from the past will repeat themselves. First and foremost, the fact that my STBXAH resented me from the very beginning when he left our hometown to move to live with me. I spent a lot of time during my own self-esteem crisis convinced that despite actions and words 100% to the contrary, my gentleman will similarly come to resent me when he and his daughter move closer to where I live this summer, because I'm just not worthy of someone wanting to do that for me.
Getting stuck in your own head is a miserable place to be. I think it's good that you can identify this for exactly what it is, and work on it from the inside out.
