When should you tell your boyfriend/girlfriend you have asperger's?

This wasn't exactly a situation I could prevent. My school forced me to go to a psychologist. She gave them my personal files (which is illegal), and they used that personal information against me.

My diagnosis was also based on a bunch of bogus questions. A couple of the questions they asked me, followed by my answers:

Q: The birthday of the person you like the least is coming up. What present do you get him?

A: Hm, I know he's a soccer fan, so maybe something related to that. But I'd probably ask his friends what he'd like.

Conclusion: I'm bad at interpreting what other people want, since I didn't come up with a concrete present.

Q: How did you feel when your brothers left for college?

A: I was a little upset. I like my brothers, and I miss having them around at home.

Conclusion: I can't handle change.

Q: How do you feel about people who bring, say, 15 items to the '10 items or less'-line in the supermarket?

A: I think that's kind of selfish. You need to draw a line. The purpose of that queue is that it goes faster than the other ones. If everyone starts bringing more items than what's allowed, the line will move as slow as a normal one.

Conclusion: I need rules in my life. Without order, I'll freak out.

Another reason for my diagnosis was my IQ test. Basically, the 'verbal' part of my brain was exceptionally developed.
The 'mathematical' part of my brain was also highly developed, but there was a difference of 18 IQ points with my verbal IQ.

So, they decided something was wrong with me. The newest studies concluded that this kind of reasoning is bogus (which makes sense. Not every mathematician is brilliant at language, and vice versa). But in the old days... that was reason enough to give you the 'wacko'-label.

As for telling mature things about yourself...

The girls I dated also thought I'm extremely mature, funny and 'wise' (not a common compliment, but that's how the last two girls I dated said it).

My situation at school though wasn't something I could prevent. They wanted to get funding for my 'condition', so they did everything they could to convince me I had mental problems.

I wasn't all alone, though. Some teachers did think I was treated unethically, but little spoke out against the principal. It's not that easy to stand up to the person who writes your paycheck, I guess...

This situation is highly uncommon (I hope), and hard to understand for most people. But I'm not trying to play the 'pity me, I have Asperger's!'-card. I try to keep standing tall. But after all that happened, I am still a little traumatized.

I wouldn't have much trouble telling women I have Asperger's, if there wasn't so many bullshit connected with it. I haven't even told the worst things here. If you will, you can read my other comments (I know they're long, sorry). Now, tell me: would you really tell all this to someone you've just met?

Thanks for reading.
