My roommate and I are leaving our current apartment. My new lease started March 1, and our current lease ends March 31. He promised to sign on to end the lease early with the condition that he found a new apartment first. I needed to secure my new apartment so I signed the new lease, knowing I may have to pay rent for two apartments this month if he didn't find something. He has a history of being inconsiderate so I saved up in preparation for this to not work out.

The problem is I recently had to drop a bunch of money on my car and I can no longer afford it. I am so stressed and I've been begging him for a full month to find something so we could end the lease early.

He only started looking for apartments about a week ago and he has really high standards. For me, I basically chose the first place I could afford. I am so frustrated because he has a history of being inconsiderate and he had so much time to prepare for this. I am genuinely so exhausted and living with him has been traumatizing. I need to leave ASAP.

WIBTA if I asked him to cover my share of the rent for the time I will not be there? I know he can afford it but it is last minute.

More details: I think I'm so upset because we were supposed to be friends and he made a promise to me that he made no effort in fulfilling so I was just dealing with a load of stress this entire month.

I gave him about a month and a half's notice to end early, which is arguably not enough time.

Our landlord wants us out ASAP so he can remodel so he offered to prorate rent for free if we left early. Our deposit has been long gone, honestly.

UPDATE: Thank you guys for the feedback. So I told my roommate that I wish he would've told me that he was unable to end the lease early at any point instead of leading me to believe that was going to happen until the very last day. I'm honestly more upset about the emotional turmoil this has put me through than my own financial planning mistakes. I apologized for putting a bunch of pressure on him because it isn't his problem. Rent is due, but the landlord is still offering to prorate and my roommate is still saying he will find a place.

We've had an incredibly rocky roommate relationship and there's a lot of baggage we're both carrying into this situation. Despite public opinion (and this officially makes me the AH), I told him I would pay rent up until my move-out date, which is like 1/4 of what I usually pay. I did this because he has been suggesting we stiff our landlord this month (not because of my finances, but because it's the last month and he doesn't like the landlord) and he is still being unclear about when he will be moving out. Rent is due and I still have no idea how much I owe or if he's planning on paying at all so I basically just made an executive decision to screw him over and let him decide whether or not he wants to figure it out himself.

Hours after I told him, he signed a lease for an apartment that he told me he likes. We're supposed to be moving out soon and he's going on a last-minute vacation so his moving timeline is still unclear, but I decided to burn the bridge and be the AH because I need this to be over.
