TITLE: Girlfriend [26/f] and I [25/m] are breaking up. Looking to move, how can I get out of lease and make process as painless as possible for her?
POST: I want to apologize if this is wrong place to post. 

So basically what the title says. Unfortunately our relationship is to the point where I really don't feel I am able to provide and be the partner she needs and wants. She would like me out ASAP, I found an apartment this morning and will be putting a deposit tonight. 

For the current apartment, most of the utilities and bills are under my name. The lease was originally for 4 years, and auto-renews every year. The renewal date is the beginning of the month and requires 90 days notice before changes can be made. Does anyone have advice on how I can negotiate with the landlord to get out of the lease? I also want to make this process as easy as possible for my partner.
TL;DR: 
Breaking up and moving out of apartment w/ a co-signed 4-year lease that auto-renewed and outside 90 days notification window. Want to move out and not cause further pain to other party. Need advice!
