Psoriasis & Relationship

I've suffered my entire life with this horrid disease. it's hard because I'm actually an attractive 25 year old female and never had a hard time with attention from men. well kinda. because I learned how to cover my imperfections, it was always a bit of a surprise to them. They would be all down for me, feel great for having a good looking girl on their arm, but then came the intimacy. I would pull away at any touch, try and stay in the shadows (so serious). lights always off. And when they found out why, they would drop me. only one guy had the balls to really tell me why. So now, I found someone who says it doesn't bother him. BUT, he's apparently said "her skin is hard to look at sometimes" to a couple mutual friends. this devastated me. I blew up and cried and pulled back from him. he denied it and swears he never said such thing. he actually tried soughting out the person who told me. What I found bizzare, is the fact he got mad at the wrong person (this person he got mad at has started drama for us in the past so that's why he assumed it was him). But it wasn't. If my SO truly said this, wouldn't he have known who it came from? He hates the person it came from (one of the people who told me what he had said), so he would have had NO problem putting this guy in place if he so chose to. Also, the person who told me this has NO reason to lie whatsoever. Like none. So idk what to do. SO denies it but the source is 98% convincing.
