Talking from personal experience, I think you should take things slow but you should also be upfront with him about your disorders because it hurts more when you get close to a person and they reject you and want nothing to do with you when they find out you have disorders. I have ADHD along with Asperger’s Syndrome and OCD and while I have been lucky enough to find two women in my life that have accepted me for them there were a few women in between my first girlfriend and my Wife that were all too willing to date me up until I told them what I had. Trust me when I say it makes you feel like **** especially when you overhear them laughing about it with their friends and I hope that does not happen to you and Ian is a nonjudgmental person.
