I fear I'm in the same boat. I've been with my SO for over 20 years now, married for 16 with a 9 year old. I'm pretty sure she's leaving me. I think she had one foot out the door at Christmas, then I was diagnosed in early January. I don't know if she's sticking around now because she is curious how I am medicated and stable, if she is guilty about leaving now that I'm "not well", or if I'm just paranoid and we are OK.
