I went back and looked through the game too, though I got distracted by real life for a bit. It's tricky because the relevant dialog is split up all over the game.
First, Maya's dialog right before the part you showed might be important, because she does imply things have changed recently: "I think we were very close to breaking up. ... Things haven't been good between us lately. My dad kept me from seeing her and that didn't do us any good. And lately she's not been herself either. She doesn't answer my calls and last time I spoke to her she said she was giving up and moving far away. She was going to come here and we were gonna be together just like before... [and so on]"
Next, we travel back in time to when the MC gets a call from Josy at the end of his first day at B&R. Josy says she still hasn't heard back from B&R: "I think I will cut my losses already and just move on. I'm actually thinking of quitting my job and moving to the east coast... Maybe start working in a mall or do volunteer work, I don't know..." The MC can then either ask about the boyfriend or himself, and Josy says calling him was a bad idea. She goes on to say "I just... feel like I need to get away for a while." The MC then asks for the second quasi-date, Josy accepts. Immediately after they hang up, Josy asks herself "What am I doing?"
Note that at this point, Josy is at least framing the move as temporary. Fast forward to the date.
After dinner, the two discuss the MC's life at B&R. The MC asks if she heard about the wait list. Josy's mood immediately crashes and she says it's not going to happen. The MC says Tina told him Josy quit the minimart yesterday. Josy breaks down crying and explains:
"These last few months have been hell, [MC]. I've been so lonely and scared. And you know what I did? I told myself I would get accepted to B&R and that everything would be great again. And I actually believed it. I almost took it for granted. And now... I'm not going to get accepted. It's like the biggest blow to my psyche ever. I get anxiety attacks when I think about it. I can't breathe when I think of being stuck in this hole, living with dad and Monica for another year! I just have to get away from here and do something new and start all over."
The MC says he had no idea she was this upset. Josy responds "Meeting you made me feel different about this... It was exciting... I felt that spark that's been missing in my life for quite some time now. Relationships when you can't be with each other every week suck, by the way... Never do that with anyone."
When asked if she misses feeling loved, Josy says "More than anything... And now... I think of just cutting all ties and moving away. *Sniffles* great solution, Huh? Hah." "It's just that staying here does nothing for me. I would have to put up with Steve every day and have no friends to hang out with, because they all moved away. Growing up sucks!"
Phew, quite the transcript. Since Josy intentionally avoids discussing her 'boyfriend' in this exchange we're still forced to speculate. But here's my interpretation.
Josy and Maya got together during the flashback at the start of Episode 4, which happened some time before the summer. This was the time when Maya claims she was at her happiest. Maya's dad intervenes and forbids the relationship in a highly traumatic manner. Maya and Josy plan to both attend B&R and this time keep the relationship a secret.
Over the summer Maya and Josy 'drift apart' due to a combination of difficulty communicating and Josy's increasing panic as she starts to think she won't get accepted to B&R. This becomes a negative feedback loop, as the chances to communicate go from being a welcome oasis to yet one more thing to worry about [Josy much later describes Maya's texts as "Each one was meaner than the one before!"].
This continues until the game starts, near the end of the summer. Josy is still stuck on the wait list, then has her first date with the MC. She had probably though about running away before this, but just as an idle thought. Now she starts actually considering it. The school year starts and Josy is still waiting. She calls the MC to say she is thinking of moving out east "for a little while." Josy doesn't want to give up on Maya, but she's starting to feel trapped. The MC surprises her by asking for a second date. She agrees, but then immediately feels guilty.
Josy calls Maya and tries to explain she won't get into B&R and is thinking of moving away because she doesn't know what else to do. This goes very badly as Maya feels like Josy is abandoning her and Josy feels like she is already abandoned. So she spends the rest of the week alternately excited about seeing the MC and guilty about losing Maya for good.
The day before the date, Josy quits her job because she can't take it anymore. I think it's part of her rationalization: she can effectively think of the relationship with Maya as doomed and her date with the MC as a one night stand before she leaves. But naturally she still feels terrible about the whole thing. She discusses this with the MC and asks him to spend the night.
When the date ends and her parents come home early (one way or the other), Josy is effectively isolated until Wednesday. At that point she learns that a) she was accepted to B&R, b) Maya is really angry with her. She calls the MC to ask to stay with him, but is told no. Josy decides not to talk to Maya until she gets there and talks things over with the MC.
Upon arrival, she is assigned a room by the college housing authority (which clearly runs directly on plot requirements!), and we get the dramatic end to Episode 3.
So there we go. That's my forensic analysis of Josy's plans. I now eagerly await Episode 5 arriving to prove me completely wrong.
(Did it work? What about now? Dammit!)
but it was such an interesting scene especially with how far she and the MC have come. Considering everything she has been accused of she ain't that bad at all.
