Not all succubi are friendly (I would say most of them are leeches but that’s just me) and sometimes you can come across impostor spirits. I don’t see why Lilith would put you through this torture. This is how spirits can play games with you… “Oh have I insulted this spirit” “Is what’s going on actually to my benefit?” Are you sure you are talking to the right spirit to begin with? You are the God of your universe and if you don’t want this succubus in your life that’s where it ends.
The moment when I had stopped doubting myself and when I recognized the succubs as my enemy is when I had started to get them out of my life. Granted, I had to get to a point of almost killing myself to get it but better late than never lol.
