She needs time buddy. Sounds like your last episode where you had turned yourself around and got your girl back then had another episode has scared her to this. Try and be as understanding to that as you can and give her lots of space.
Can you leave info on your illness out for her ? She may read it, she may not !!! How old are your Daughters ? I know you have apologised to them, but have they seen the info on your illness ? I imagine they were also very scared so it might be firstly a relief to them, but then they may speak to W about it.
Your in an unusual situation here sir and can't say that about most on here. I don't think it's all gone for you, just keep doing what your doing and the things that have worked before. The going out is quite possibly partly an escape and to get away from you, my W does that also.
