Zeke and Zelda have been together for three years, but they have had a troubled romantic relationship. Throughout their years together, the couple has resided at So Posh Apartments, a very upscale complex. Zeke and Zelda have split their lease payments, 50-50. As their annual lease renewal period approaches, Zelda decides that she cannot commit to Zeke for another year. When Zelda shares these feelings with Zeke, he quickly offers to pay for the entire year if Zelda will agree to stay with him for the coming year. Zelda accepts the offer, and the two of them put their agreement in writing, sign, and date the agreement. Zeke assumes the lease on his own (Zelda is not listed on the lease with the landlord) and makes the necessary payments for the next six months. At that time, Zelda tells Zeke, "I've had it" and leaves without further explanation. Zeke sues Zelda for breach of contract. Is Zeke likely to succeed in his lawsuit? Why or why not? Explain.
