I've been going to gym, quite happily on my own for around a year. I noticed 6 months ago that my neighbour was also frequenting the same classes. Along with aspergers I also have BPD and social anxiety so I don't tend to mix very easily. It took us months to acknowledge each other but once we did we became quite friendly. She's a lovely woman, very sociable and gets on with everyone. Anyway to cut long story short we're at the point now where we text each other to arrange to either go to gym together (car share) or meet there. However I am absolutely shit at replying to messages and sticking to arrangements. 8 times out of ten I don't go when I say I'm going and half the time i don't reply to messages. I don't mean it badly, it's just that when I receive a message that doesn't have an obvious reply I don't see the point in replying. DH often points out that I'm being rude but I don't mean to be! Anyway I would hate her to think I don't like her or value her friendship, so do I tell her that I have aspergers so find socialising difficult? Her son has aspergers so she might have already realised but I'm worried I'm just coming across badly. DH says I shouldn't overshare so im not sure what the right thing to do here is!
