Roommate ghosted me

Not bothering with a throwaway because I doubt she'll see this and I don't care if she does. Sorry that this is a long story. I need to share it somewhere because I've been seething.

My roommate and I were part of a circle of gaming friends online. Moving in together started out as a joke that gradually became reality because we both wanted to move and the timing lined up. We were both moving to a new state, but I can work remotely from anywhere and I make pretty decent money so I could afford a two-bedroom apartment by myself. I didn't really need a roommate but she was coming from a not great living situation, so I told her that she could move in and find a job once she got here. I didn't mind covering rent for a few months.

She also moved with basically nothing. I bought her a bed, a desk, and several other things. I told her I didn't need her to pay me back and that just finding a job and splitting rent and bills would suffice.

We lived in that apartment for a year and despite checking in with her and offering her a lot of help, she never found a job. I offered to help her with her resume, to help her find things in the area. Her ID expired and she was offered help to take care of that more than a few times. Not only by me, but by friends that lived close by. Occasionally, she would look for jobs or send out applications for about a week, and then it would stop.

The apartment itself ended up being a shithole. That is a whole separate story, but basically my life was hell the entire time we lived there. But in the year I lived there, rent ended up skyrocketing and became so outrageous that, to make a long story short(er), I ended up buying a house. I could still afford it on my own but finances became much tighter, so I had a serious conversation with my roommate about finding a job. I gave her an ultimatum, that she needed to find a job and start contributing financially by the spring or she needed to find somewhere else to live.

She never found a job and I don't even think she looked for more than a few days. It's on me for never finding the spine to actually tell her to leave, but I thought we were still friends and I didn't want to send her away with nowhere to go. However, my partner and I had started talking about him moving in with me and so I finally told her she needed to find a new place by the end of the year.

It was a surprisingly good conversation. She told me she was talking to her partner about moving in with him.

She left to visit him earlier this month, around the 9th. He lives about 6ish hours away so she flew to see him (she finally asked for help to get an ID when she needed one to board a plane). She's completely stopped responding to all of my messages, hasn't told me when she's coming home or what her plan is. All her stuff is still here. I know she's alive and well because we're in a discord server that she posts in.

The most she ever helped was doing the dishes when I asked her to and watching my dog and cats on occasions where I was traveling. I appreciated those things and still do. But I'm pretty hurt and confused by the whole thing, and this whole situation just sucks.
