My son is 27 and has Aspergers. He has had a couple of girlfriends, one for about 9 months. His current girlfriend is really lovely and they've been a bit 'full-on' for the last 8 weeks.
Last night he asked me "how do you know if you really like someone" and "how do you know if you are going off someone".
I tried to answer as best I could............but what would YOU say?
