I know someone who went through this, and when they did find someone they wanted to marry, they felt SO GUILTY that they got the opportunity to start again with someone else and not the late spouse, and so guilty enjoying moments with their children and someone else... it's true that some people never get over it. Even if Danielle gets it, and they work out, he may likely still have lots of pangs of guilt over the years.

I googled them to learn a little bit more about his marriage, and there are images of them together VERY young, so I'm guessing this was his first love, and she died at only 24 (in 2019 after being sick for 2 years, and they already had their baby so it's a really young first love that started in their teens), and he came onto season 17 soon after. I wonder if part of his guilt is that he thinks he started looking too soon? (like maybe he thinks he should be alone longer to honor her, but also feels like he'd like someone to share special moments in his family with?)
