Thanks for your reply! I'm sorry you and your partner went through this, but I'm glad to see you found solutions that worked for you guys.
With regard to the job, I've been supportive in every way I know how, including the ones above. I am a journalist and write a bit so I helped her put together a website for herself and her work, co-wrote a comedy sketch with her (she works in TV production, but she wants to do her own show), helped her film it, score it, edit it, produce it, etc. It was great to work together on it but it was really about producing an example of what she's capable of for prospective employers. Her industry is tough, I'll give her that, but there are other related industries (film, game, book, etc.) that she can transfer her talents to if the current one is not working. I've gone so far as to get her resume into some journalism positions that require knowledge of TV production. All of this has been suggested and/or done for her, but she never seems to chase any of this on her own. I can only do so much for her; she needs to put in the effort if she wants change. And this is what scares me: what if she doesn't want change? What if she's perfectly fine complaining about her career for the rest of her life? I know people like that and I can't handle that kind of sustained negativity.
She moved into her current place last year. I spent every lunch break coming through apartments to send her. I went with her to several apartment viewings. With regard to the roommates, I'm pretty friendly with them and have gotten them to listen more seriously to her issues and work on solutions. Things have improved in some areas but not in others. But, again, the point is that having good relations with roommates sometimes requires work. Just like bettering one's career requires work. I hear a ton of complaints and don't see a whole lot of work.
I need to have the conversation you had with your SO: taking steps. I will support 100% so long as I see her taking steps. But if she's not willing to do the work to make things better, why do I have to hear about how bad everything is all day every day?
Thanks again!
