Okay, start with the first "you idiot" for lying about being divorced. You sound like you paniced and thought that was the best solution. That sounds like it is in the past and unless it's still being brought up as an issue then I'd try to forgive YOURSELF for the white lie.

I don't really have any mental illness - well not extreme illness anyway.. the eating disorders and depression are mostly under control - so i can only offer opinions about how she is feeling and how you can help her.

You sound like a really great guy, from what you have posted here and the replies you have written on other threads.

If she has started new meds it will take a while for the dosage to build up and for her to get back a stable 'emotional' level. You will hear the smile in her voice again eventually. For me I have just come off antidepressants, felt it was time and all out of my system properly now - it's starting to make me wonder if what I feel right now is the REAL me because so far I fell like a horrible person.

You give her the openings to express how she is feeling, just give it a little more time with no pressure and she hopefully will open up.

Just being there as you have been, telling her you love her and reassuring her that you are not going to give up might just bring back the laughter.

"flight or fight" instincts are powerful, very possible that it's just a gut reation for her to want to leave so that she doesn't get hurt.

Hope that everything works out as you do deserve the best x
