I dont understand why he's crying now. You don't neglect someone 10 years to then cry when they move on. It's not that he didn't love her, she was living under his roof and he must have not once asked about her to not know anything. Any decent person would've talked to her, at least 🙄 and if she is your fiancé, dude, make an effort to be decent, you don't need to be charming, just polite!
