Thanks PinkPig, Nadya, fuchka and starlight1 for your kind words!
It's been difficult, living with my ex and trying to process the break-up at the same time. Our friend Will moved in a couple of weeks ago, into rory's room. After that rory has been sleeping on a mattress in the kitchen and hanging out in whatever room happens to be available. That really got to me, I felt like I really needed some space from him, but he was always there where I also wanted to be. I talked to rory about it and we made a plan. So, rory spent about 4 days at a friend's place, and when he got back, I went to Yvonne's place. She's travelling at the moment, so she said I could use her room while she's away. Her housemates are really nice and they've welcomed me with open arms, so that's cool.

I'm planning on staying here for about 5 days. After that me and Hank are going to spend another 5 days at his parents' place for Christmas and after that I'm going to Home Country for two weeks. All of this gives me and rory plenty of time to not see each other, which I'm sure will help.
I've been doing a lot of soul searching, trying to figure out what I need to work on. I came across this article:
https://www.howtoforgivepeople.com/how-to-overcome-emotional-dependency. It's about emotional self-reliance and I found it really helpful. I've struggled with being alone a lot and that's just gotten worse recently. It's really good for me to stay at Yvonne's place and just be on my own, face any daily challenges I have on my own. Since there's no one I can rely on while I'm here, I have to develop certain skills. Like figuring out what to do when I'm bored. It's weird that I've gotten this way because I have lived alone (or with random housemates that I didn't know) several times and I did OK. I think it's much worse to miss other people when they are just a couple of doors away than if they are not in the same house at all. The latter is kind of easier to accept. But I think I need to start having some me-time regularly, regardless of when other people want to be with me. So far I've just
endured alone time and have felt happier the moment someone knocks on my door wanting to hang out. But maybe I should start seeing it differently, as a tool for growth.
I also really want to work on my resistance over two people I love also loving each other. I mean, I'm completely fine with people I love loving other people than me. As long as they are not the same people I also love.

I really want to change that. I feel like that is something I've held on to for a long time, as something I have known that I
would struggle with if it ever happened. And when it did, of course I felt bad about it, after having convinced myself for years and years that I would. It's a self-fulfilling prophecy.
Also, relating to the previous thing, Hank and rory have started dating the same person! I'll call her Dahlia. If the timing wasn't this, that would be hilarious and/or cute. Right now I just feel like I'm being replaced as their shared partner. I'm trying to get over that, because it looks like Hank is really into her, so this might even be a long-term thing. Which is also new in mine and Hank's relationship since while he has dated a few people, it usually hasn't lasted for long. This seems to have more potential for a serious relationship. I don't really know how rory is feeling about her, but I'd guess that their thing is non-sexual because of rory's orientation. Then again, who knows, his orientation changes every once in a while... Anyway, it's a challenge because of the circumstances, for sure. But I'm trying my hardest to work on that as well.
