I didn't say that Zoey was evil for doing it, but the characterisation from the Interlude is that she put more emphasis on chasing her dreams than whatever she had with MC. IIRC she even mentions during the Interlude how she didn't regard it as serious as she presumes Fuckface did.
Regardless of whether she still thought about him or not, she was still happy to stop communicating with him (which is more than simply cutting down) until her dreams don't pan out and she comes back into the picture hoping to pick up where she left off but quickly finds that the MC has actually moved on pretty substantially.
It's true that after the passing of Zoey's grandma her main objective is to realise her dream, but she doesn't wish to end whatever she thinks she has with the MC. Zoey wants him to come with her. She's very sad that he can't but feels she has to do it for herself anyway, hoping to prepare a nest for both in San Diego that the MC can join as soon as he's graduated. After all, they've made plans to move away to some warm place together. Don't forget, Zoey is mourning fresh after the death of one of the dearest people in her life. It's not fair to expect someone in a distressed state to act reasonably, is it?
A very important scene of Zoey's story worth paying special attention to is the conversation with Bret while getting her first tattoo. It's during that scene where she reveals her version of their relationship, where Bret tells about his similar experience and how avoiding contact with Emma seemingly worked out perfectly well in the end (it didn't).
Zoey claims they're best friends who just happen to do what couples do (during the course of the story the players are constantly shown she's clearly lying to herself without realising it). She's unhappy about things being awkward between them, that the MC isn't very talkative (yes, it was actually the MC at first who didn't want to communicate and Zoey had to initiate conversations) or sharing her joy. Bret, telling about his own experience puts a thought in Zoey's head that perhaps the MC has deeper feelings. He tells about a similar story between him and Emma, how he stopped talking to her and how they're back to being best friends.
Zoey, with Bret's words in her mind and hoping she's doing the MC a favor, starts writing him less and less in the following months. However, she's not doing it
happily and it hurts herself as well. For example, you can read in Zoey's diary how badly it affects her that the MC didn't send her birthday wishes (which must be around the time he changed his phone number).
Again, it's still a positioning that in most paths Fuckface does at least confirm there's dating going on, so most importantly it's Zoey finding out that Fuckface has likely moved on, and it's from then suddenly she not as chill as she was in the previous episode and is in fact wanting to declare her love.
Zoey doesn't want the MC back because of finding out he's in a relationship. When he tells about his relationships during ep10 hangout, Zoey is genuinely happy for him. After all, that's what she wanted him to do - move on and think less about her to spare his feelings. Upon returning home all Zoey hopes is to be on talking terms and hang out again, she even suspects he could be mad at her for what she did. It's only during the BBQ talk (which Zoey initiates as she's now more ready to talk about feelings as of her character arc) where the MC confesses his past feelings that makes Zoey reflect on their relationship and realise that she's also cared about him more than just friend all this time, and now she can't stop thinking about it and keep those feelings hidden from herself. It has nothing to do with the MC having a girlfriend or moving on in other ways.
This is what I don't like about Zoey's characterisation and is why I personally find her quite... well boring as a result. If her whole thing is simply two inexperienced teens who were or weren't fucking yet awkward around their feelings but now want to get together with Fuckface in the pursuit of love then how is that really all that different from say the throuple, Jill, or even Quinn? In my view DPC unfortunately brought her in too late and since then has involved her extremely little in the ongoing events of the game to the point many have joked about how she's basically been benched since the Interlude.
It's why I probably have the different read on her where she's unintentionally this relationship wrecker because of insecurities she has as that would actually be a unique characterisation for this game and lead to some interesting scenarios as a result. It could lead to interesting conflicts with other characters that actually hinders Fuckface in future episodes, see Zoey almost grow resentful now that she's got what she thought she wanted but in reality didn't etc.
If however she's just this "Fuckface's first love now realising she wants him too" true love trope then it's just going to be at the bottom of the list for me interest-wise.
Hey, I'm not trying to change anyone's opinion about Zoey. Whether another person loves or hates her, enjoys her story or finds it boring, that's totally fine by me. Unless someone tries to twist the story events and spread false information (whether it's due to bad memory, blind hate for a character or whatever) I don't care. It's not like someone disliking my favourite girl would somehow hinder my enjoyment of her story.
Au contraire, it's actually quite entertaining how Zoey's haters can't stop thinking about her and feel the need to constantly remind everyone about it and their insecurities. It's especially fun when I succeed in triggering them even further
