Hello !
I am new here, also quite new to Astrology but I have been reading alot, "the illusion thing" is more related with Neptune I think. What I read is that you idealize your partner too much, is a dreamy feeling there is an inclination to illusions and delusions. I have also experienced this and is different from Pluto, Pluto is intensity.
I have also experienced venus/moon pluton, I can say that is a very itensive feeling, you realise that you have never felt this way before and you are surprised of the deept of your feelings, but the feelings are so strong that you can barely keep with your normal life. The problem is that , that intensive feeling can be destructive and also it's impossible to keep on that level for ever, so it could happen that one of you two do something drastic to liberate from it, or when that intensve feeling decreases it could leave a feeling of confusion, you don't know whats going on, its something new. Then its when is important for you two to get used to the new feeling and go trough all that torment, and then Voilà something beautiful might happen.
I just imagine because I couldnt make it until there unfortunately..nd I talked from my experience
(english is not my firt language btw
)
I would be happy to share more experiences and opinions about it!!
