Thank you very much for the replies... nothing much has changed; my wife decided she was going to call the center today to more or less at least make them aware of her concern and so they would be aware of the situation. Unfortunately the manager who she needed to talk to had gone home early.

She's going to try again first thing tomorrow morning and then text me to let me know how it went (since I'm due to go in at 9:30)

Received 2 more texts from the woman... have not responded for now... will leave it till tomorrow and see how things are then.

Edit: Wanted to follow up on the following reply as I guess it did raise a point to address:

A bit yeah... she puts me in awkward situations verbally as I don't know (perhaps down in part to my ASD) the best way to respond without dropping a clanger. In addition to that, things had come to point where she was becoming very suffocating... however strange this might sound... like I was the only man/person in her life and if I didn't correspond to her expectations she would have a massive melt down.

What's worse is that I didn't really recognize it progressing to that level... it was my wife who pointed it out... and as far as I'm concerned, my wife is my world. I don't want anything to jepodise that... likewise, I have become uncomfortable with the notion of being alone with this woman... a kind of fear that she could go bat **** and throw accusations my way. Truth is, I would never do anything inappropriate... but the fear of being wrongly accused if I wasn't to do what she wanted, worries me... I know this is a fear that hasn't happened and is probably irrational... but it's there. Is part of the reason I suppose I have kept acknowledging her.... just writing this just feels so stupid and I hope that it doesn't offend anyone. I think people from both genders are capable of manipulation, so I am not trying to insinuate that she might do this because she's a woman.... I think it's more the opposite gender situ... and could easily be vise versa.

I did and do like her as a person... but she is going through a very unbalanced time right now... just as I am I guess (though things have been improving)... and she does have huge knee jerk reactions to stuff.

I guess the other fact is... I just don't know her well enough... for the most part my main interaction with her was for a month or so while in hospital and then the rest was by phone and text... I've never really seen her outside of the context of hospital, so I don't know what she is like with other people or why in some case they have come to avoid her.
