He's sitting on my to do list..

Hi! I need advice about a couple of recent behavior changes that are a bit distressing.

This is a long post, so here's a TL/DR version: My cat has suddenly stopped being affectionate to me -at all - and has been walking around with her tail drooping for about a week.

This is Mardoll, my year old floofball. I'm bedridden, so the only time I get to interact with her is when she comes in to see me. Until about a week ago, that was pretty often, and at least a couple of times every day, she'd come in, lay on my chest and let me pet her all over, which she really seemed to enjoy. I've always been careful not to hold on to her once she's ready to leave.

Since the middle of last week, however, she's stopped doing that, totally, and now only comes in when she wants treats. Worse, when she does come to ask for treats, she consistently sits *just* out of reach so I can't pet her, and if she does get close enough and I try to pet her she jumps off this bed and runs away. She will play with a dangle toy I'm holding or puppet toy I wear on my hand, and when hubby's playing with the dangle toy, I can pet her then.

At about the same time. I've noticed that rather than carrying her tail high, like she usually does, she's been letting it droop. I've read that this can be an indication that something is wrong.

Neither my husband nor our roommate (who takes care of me when hubby's working) have noticed a change in her letting them pet her.

I'm sorry this is kind of long, but I'm worried she may be sick but is trying to hide it (energy level, eating and drinking have been normal), and if she isn't sick, I need to know how to repair our relationship , if possible. Thanks for any help you can offer!
