Like even he himself acknowledged that she doesn't has a choice in marrying him, like come on bro
this fuckass ml literally sees her be happy for the first time and thinks "no i cant let her leave me!" despite neglecting her for the entire engagement ヽ(`Д´)ﾉ
Look, he had a nightmare about her rejecting his gift. This guy has the emotional stability of soufflé.
If he'd heard Nicoles inner thoughts about having to marry "ANOTHER problematic individual" if her engagement with him falls through, he'd evaporate in self-pity
and he's kind of tangled several steps before reaching the conclusion that he won't get anywhere if he keeps on harping "but you're MY FIANCEE" because she knows, she knew to begin with, YOU forgot, nitwit
And now she got CHOICES.
The fact that she's finally happy and finds an opportunity for herself and then this fuckass man who suddenly remembers he has a fiance says she can't. LIKE FUCK OFF
