How is it that I get the most attention from women when I am at my worst?

So I have been very self conscious of my weight and appearance and I have been working on it with the help of my therapist. Then my back starts killing me and I gain a little more and I acknowledge I’m self conscious, then I start seeing this really sweet girl, and I lose a good amount of weight. This week I gain some back but the therapist was not too concerned. Then I have a few people, two men and a woman, compliment my appearance. Then today I hit my lowest weight since the start of therapy and before my back issues, and I walk into one of my classes and this woman who is pretty attractive (for my preferences) actually tries to flirt with me. Now to be clear I have not been trying to lose weight to impress anyone. It has been a tough uphill climb and I am proud of the progress I have made, especially with my health in the clear. I am a big believer in being healthy at any size. But I am a bit confused how I can be at my best and not really get any attention, while I am at my worst I get more.
