I feel for you, notanaturalblonde and I'm sending you good wishes for a full and quick recovery.
I agree that maybe you should stop all your contacting, and your husband can do it. And stop giving advice too!
I met someone 25 years ago and always thought of her as a really good friend, we got on well and enjoyed each others company. However, over the years I realised it was always me who made contact, never, ever her, and eventually, a couple of years ago, I stopped. I haven't heard from her since, though I know that if I messaged her now, she would be happy to meet up again sometime. Someone once said that maybe she's happier if its always me who makes contact, but she does regard me as a friend because we do meet up when I suggest it. However, to my mind, any relationship should be a two-way thing - give and take is what it's all about, maybe not necessarily in equal measures as people/life is never that straight-forward, but it should never be totally one-sided. I decided to go out and make new friends instead - U3A, and a local friendship club, and I now have a brilliant friend who treats me as I do her, and we have consideration and respect for each other, and I know she'd be there for me, as I would be there for her, if ever we need support. That's what friendship is all about, not someone just taking advantage of 'using' someone else when it suits them.
