Is she requests to follow him on social, will he accept and follow her back?

The risk in doing that was giving her a blow to her self confidence.
Give him time, anyway.
But she should back away for a while.
And keep on with her therapy... with the mirror!

Thanks Elena J, will keep you posted! Even I'm doing the mirror exercises now.

Final update: He never accepted, she withdrew the request. He still checks on her regularly online and she hasn't blocked him but this ended up being a no because she never attempted to connect again.
