Why do guys think that breaking up with their partner while they are going through stuff at home is going to make things better in any way?

My boyfriend and I have been dating for over a year I'm 18 he's 17 turning 18. He has been going through stuff at home and he won't tell about any of it and keeps pushing me away. I'm trying to do everything thats gonna help him he asked me to give him time I do that, he doesn't wanna talk about a certain thing I dont push it further. I've been doing everything so he feels comfortable and is able to open up but it just never happens. Now he's sending me reels saying "guys break up with the girls they love the most when theyre going through stuff at home" It just doesn't seem fair at all. And I don't know how to tell him to man up and stop running away.
