Was it love or a fetish?

I'm afraid of being a fetish. My way of loving is very intense, I wouldn't say obsessive, I think. I had a relationship with someone very special, but that relationship ended, it still hurts, I don't know if I miss her. The point is that she wasn't mentally well, she had the desire for someone to be obsessed with her, for someone to be obsessed in a morbid way. I never had a problem with that desire of hers, I hadn't paid much attention to it, but over time, for some strange reason, I began to fear that she only wanted me for the way I loved, which, according to her own words, pleased her desire. I clarify that I don't consider myself an obsessive person, I think, I don't know. One day I asked her if she loved me or if I was just a fetish, to which she replied that she obviously loved me, she said it in such a sincere way that I believed her. Over time I realized that I was the only one who put effort into the relationship, the only one who tried not to lose her. After ending that relationship, I started thinking and came to the conclusion that maybe she didn't have bad intentions, maybe her mistake was confusing her fetish with love.

 I can't express myself, I hope you understoo😭
