Tallulah peed on the couch tonight!!!!

I cannot believe it. She has never peed on the couch. She did it right in front of my husband and I. I was surprised because she sits on the couch frequently and she is welcome to sit on the couch (we decided to pick our battles). Why would she pee where she sits all the time to relax?! She has also been peeing on her rug where we keep her food and water bowl. I don't get it at all! Why would she pee where she eats?! This problem is much worse than I thought. Its one thing to pee on the floor but I cannot deal with her peeing on our furniture. I read everyone's advice and a lot of it was very helpful. I know we need some professional help here but we just cannot afford it right now. I just got laid off from my job a few weeks ago. I am starting to really wonder if we need to rehome her. I hate to do it but I'm not sure we can give her what she needs at this point. On the other side of things we have trained her to sleep on her pillow rather than on our bed! Small victories! And we are working on some basic obedience training and walking on a leash. She is doing okay, its hard for her because she is so used to not being obedient and not being walked at all. But after tonight I just don't know what to do.
