Is OTHER wrong in the post ? POST : In August I moved in with two of my high school friends and a friend of a friend (FoF) who needed a place to stay. In September or October we signed an agreement to live together again because our rental agency wanted to know if they needed to start showing our place. We had talked about living together before and after signing the agreement, and at no point did anyone hesitate to agree. It's not a legally binding lease, more of a gentleman's agreement that reserved our apartment for the next year. 

This past weekend one of my high school friends and FoF told us they're moving out at the end of the current lease. I'm not as upset with FoF because she understands that what she did isn't cool and she fucked us over, but my friend doesn't think he did anything wrong because we hadn't signed an actual legally binding lease. Since we had agreed to live together again I didn't start looking for housing until now. Of the 13 properties I have inquired about (a total of 40ish units) I've found 3 units that are available. Most people sign leases in November/December for August move in dates so it's pretty picked over.

I'm not mad that they want to move out. I'm mad they backed out on our agreement to live together, waited until now to tell us (leaving me with very limited options for housing), and that my friend doesn't understand why I don't think what he did is acceptable. So, Reddit, give it to me straight: Am I the asshole or is my anger justified?
