well, if its the case that you have SA serious enough that you need to have this conversation, chances are your sa is very obvious anyways, and you will have to explain your actions and shy behavior almost immediately. We had already broken up, when I started to say more about how I didn't know how to talk very well, and was really shy..she just said "maybe your autistic," "I can never talk to you, you don't know how to have a conversation!" are the things she said to me..I told her it really hurt me when someone tells me that I can't talk well, because I like to believe I've made a lot of progress with SA, and when someone close to me tells me that I haven't, that really hurts, and brings me down. and as far as the relationships, in most cases It is what it is; whatever sa makes you do, its who you are, there is no excusing it just because your working on making it better..if it makes you less interesting, less conversational, then you are these things, and confessing your sa is fine, but it doesn't really change anything....just my experience..
