“I have no choice but to become a completely despicable woman”
yes you fucking do. Please, I thought you were rational. you had the wisdom to see your faults and to understand what happened, and to be able to blame yourself. You’re smarter than this mate.
On another note, Eiji’s mum is good for protecting her son, but when you try and push an apology away (ie, acknowledge it, you don’t have to accept it but at least allow her to apologise), bad shit happens cause they spiral and make increasingly irrational decisions. She’s a teenage girl, people make mistakes. I mean this was a pretty bad mistake ngl but you still use a mistake to teach people. With some people that requires heavy handling but with someone with this much will to better themselves it is better to accept now, and the harshness comes later.
The mother had every right to refuse entry as well as enact what's essentially a total blacklist ban to not only their home/business, but also their entire lives. She may have known about the cheating beforehand and made some assumptions, but it's totally logical of her to be on her own son's side after the truth was revealed.
I don't know how long it has been since the breakup, but with how distraught Eiji was before Ai came into his life, letting the ex see him now will only reopen wounds as well as make things even more complicated for Eiji, the ex, and even the mother for even allowing the latter in, hinting that the breakup was her own son's fault and that she's on the ex's side, and that is
not what the mother should be doing here.
Also, while people should learn from their mistakes, sometimes that's not always the case, especially if they're going to make that 'mistake' again. There are times when they will need to get by reality with a rod,
hard, multiple times, even, and have them hurtling to the very bottom before they finally realize how much they screwed up before deciding to better themselves.
Here, the ex wasn't apologizing to make amends and better herself. She was desperate to reclaim what she lost after she was caught. There was
no guarantee she would ditch her scummy new bf to get back together with Eiji, especially after what we saw she did after running back to her home. Not confessing what happened with them to her own mother, oblivious to everything, before going into that self-deprecating monologue yet still running to her scummy bf further proves how
little she feels guilty about everything, and is just addicted to the self-destruction that's ahead of her. She should
not be around Eiji for that.
