<human>: Can you provide a brief rundown of the text in within 3 sentences?

Female, 24, broke up with Male, 28, after 3 years. We've lived together for two years. We moved out of a cheap, shitty, month-to-month place into a nice place with a year lease. Three months in and I am more unhappy than ever and have decided to move back home and break it off with him. We still live together pretty civilly for now. We've been friendly, semi-still acting like we're in our relationship while we both figure out the moving situation.

He just realized today that we would be splitting the cost of breaking the lease, rather than me paying the full cost by myself. I have a full-time steady job, but I make about $200 a week. His job is not steady--though he always seems to find work--and he makes about $600 a week. Rent is $850 a month. 

I argued that he can afford to live here without me, thus it is his decision to break the lease, which costs $1000. I am more than happy to split the cost, but he thinks I should pay in full, because I am technically breaking the lease by leaving, since my name is on the lease. 

I don't think this is fair. We have always split the rent and bills perfectly even, even though he makes a lot more money than I do. Even if he is unable to find work for a period, he can file and receive unemployment for that time, and he also has a savings of about $6,000 that he can pull from.
<bot>: Should I pay in full by myself to break the lease since I'm the one leaving, even though he can afford to live here by himself?
