I want a faithful man like him like the dude worked so hard to make money cause his fiancé liked money and he still liked her when she was a total snob

By the FL's flashbacks I never saw the prince liking her, even then, the FL said that she tried everything since 10 yrs to get the prince's attention and love and he was avoiding her. I know is just a misunderstanding but we haven't seen much from the past from the ML's point of view, but his lack of communication since till now makes me think differently. Maybe now he's becoming attractive towards her? .

She was just throwing money at him to get his attention, which he clearly mentioned at least a couple of times he had no attachment to. I can completely understand why he would think she believed their relationship only relied on money. And thus why he worked hard to establish himself from the start of their engagement til now, then even harder for the last six months to clear the debt he owed her so they could start over fresh.
His lack of communication is clearly just due to his personality. When he speaks to his aide, it's quite clear that he doesn't think the FL will misinterpret his words or actions.
One last point on this subject, remember when the aide talked about unusual taste and both the og owner and the FL (in all cases I'm just using these terms separately to delineate the moments before and afterJulianne recovers her memories, respectively) misinterpreted it as delicacies? Pretty sure the aide was actually referring to her. So another example as to how this isn't as out of the blue as you think.
To Wolf and Mece: I know right?!?! This ML is absolutely squee worthy!
Ah-juicy was too focused on his forehead cause he was injured then the food
