I am suing my landlord for Breach of Contract, Unjust enrichment. Mediation will be in a month. I want an opinion on the law and merits of my case.

The landlord delayed repairs to the bathrooms and misc other items for 6 months, and has refused to repair the oven, stove and microwave. The lease agreement requires them to make these repairs. During this time we have paid full rent and therefore we are not receiving the benefit of the bargain. We have been told we can get out of the lease on the basis of breach of warranty of habitability and/or breach of fit for a particular purpose. However, we have been here for 5 years and are planning to move out in May 2014 when the lease ends. Moving out now would be very expensive for us. If we withhold rent they will file a Forcible Entry and Detainer case, our defense would be breach. This is risky if were were to lose, putting us out on the street, and not getting our damage deposit back. We can't take that risk, it would just increase our damages. Therefore, we are choosing the remedy of staying here and suing for our damages. Our suit is simply breach of the lease contract and damages?
