I am so sorry that he renewed the lease and seems so fearful about taking a risk. Yes, work on you, step that up a notch, what more can you do for you?
Since the two of you are exchanging thoughts, I think it would be a great time to tell him your feelings and thoughts on everything. Not necessarily sucking him into a R talk, just stating what you want, need, are hoping for. It seems like a lot of that has been seeing the light of day. Maybe if he knows that even after a year you aren't giving up will put the tiny bug in his head that there is still a chance to save this m when he is ready.
It doesn't sound like you are going to do anything legally, I hope you won't, as it doesn't seem important to you and he seems great with the finanical arrangements. Take some time for this to sink in, sounds like he is still confused and just needs more time, but also feeling guilty that he is holding up your life.
