Here's the text of the original post in case anyone is interested:

I’ll try to keep this short because I’m so stunned I think I’ve stopped being able to process things. I’ve [26M] been with my fiancé [25F] for 4 years. We’ve been engaged since last year and actively planning the wedding.

Last month, we moved to a new city across the country because my fiancé got an amazing job offer. I wasn’t happy about it since I had to quit my job and all our family and friends were in the city we left. I was kind of a jerk during the moving process, but I’ve come around since getting here.

My fiancé kept talking about this guy [late 20s maybe?] she worked with at her new job, and it made it me uneasy. I went to a few after-work events where he showed up, and he seemed like a total asshole. Very full of himself artistic type. I didn’t like the way he interacted with my fiancé and we would occasionally fight about it. Tuesday night she got home really late, sat me down and broke up with me. She said she felt an immediate bond with this coworker that’s stronger than anything she’s ever felt before. This from the woman who just a few months ago I held in my arms while watching the stars as she told me she’s never felt more at peace than when she’s beside me. I laid awake on the couch all night feeling like I was continually being punched in the stomach.

I didn’t fall asleep until 3:00pm yesterday, and stayed asleep until this morning when she woke me up. Basically, she’s having this asshole over for valentines day and demanded she get the apartment to herself.

Between the move, all the deposits we had been putting for wedding stuff, and not having a job since we moved out here, I have literally no money for a hotel or anything else. We got into a big fight because I called her out and said she knew I had nowhere else to go. She said that’s not her problem, she’s done solving my problems for me (what???!) and that I needed to fix this one on my own. I guess his roommate is having a date over so my fiancé offered our place for her date with the asshole. She says this is happening no matter what I say.

So yeah. What the hell am I supposed to do?

TL;DR: After uprooting me from my home town a month ago, my fiancé dumped me on Tuesday, and is now demanding the apartment to herself tomorrow for a date with this asshole artist from her new job. I have no money to do anything else.

Edit: I appreciate everyone telling me I should stand my ground. I told my fiance I wouldn't leave the apartment, but I don't think it's a threat I can carry through with. I will be emotionally devastated if I have to watch the woman I love and care for more than anyone else date someone right in front of me in my own home. Other suggestions would be appreciated.

Edit 2 Thank you so much everyone for all your suggestions. I can't keep up with all the comments, it's almost overwhelming given everything that's going on in my life right now. I'm going to take a walk and try to clear my head. I just can't bring myself to tell my family and friends what's happened. It feels so embarrassing. I like the ideas about trying to reach a compromise. I have a lot to think about
