Wife Refuses Intercourse

I haven't had intercourse with my wife for 2 months. She states that I need to fulfill her desires first (getting a job, fixing my health, being more nice to her). I am working on my education but I am actively look for work now. I have been working on my health and I do not have any major health issues just am overweight. I have been nice to her but she just asks a lot from me. I pay all the bills even though my financial situation because of my lack of a job is strained. I never have asked her to pitch in. We were separated for a while but now we are back together. She said she wants to wait until I fulfill her desires and then she will "think" about having intercourse or being affectionate. I am so sick of her; I want to leave her but I want to be more stable financially and mentally when I do. Right now I am working on become that way so when the time comes I can leave more easily.
My question is: if she is withholding intercourse, does she have a right to do so based off the scenario mentioned above? She always acts like she is religious but she only picks and chooses whatever suits her way of life (ie: backbiting, wearing heavy makeup or leaving me for many days to visit her parents).
