So you're changes are proving to bare fruit congratulations great news, why do the in-laws like you? Because of you! You're a good person who will do everything in his power to get the most important person back from insanity, no bad thing.
Being able to communicate when she chooses could extend her A, I know how hard it is not to stay in touch BUT feeling the void could be beneficial. Do you pursue her or does she do all the pursuing? Ideally let her pursue you it will happen but can totally understand you wanting to stay talking to her. Thinking about this maybe don't listen to me at all who am I to know, I would hate to add to your problems but it is a common theme.
People need to understand limerence and how it affects the brain, she basically is not herself due to these chemicals BUT IT ENDS and being that safe place with strong boundaries is showing positive signs. Good for you.
I am quite new to all this and hopefully I will learn much from DR especially about validation and communication and also see lots of good information on these boards, thanks all.
The people here are really helpful and am sure you are using the information to help you succeed.
Stay strong stay with it and good luck.
Mark.
