Why am I having mixed and confused feelings?

There was a time when I was married and was in a very dark place. My ex husband was abusive and my marriage was hell. My brother was my biggest supporter. He was there for me through all of it. I got divorced and haven’t dated anyone since.

Now, the more I search for love, the more I long for a man touch, the more I want to be with a man, the more my brother comes to my mind. If I tell myself that I don’t have intimate feelings for my brother, I would be lying. If I tell myself that I’m not sexually attractive to my brother, I’m not being truthful.

But why am I getting these mixed and confused feelings? Like I know being with my brother is wrong, but it feels so right.
