Sick and tired!

Of my husband telling me he’s going to leave me...Everytime we get in the most minor fights he tells me he’s gonna leave me I’m a waste of space etc... He always winds up apologizing and saying he doesn’t mean it but it’s at least 2 times a week this happens. It’s making me really unhappy and insecure but I am not the type to beg a man to stay IF You wanna walk then walk I will never chase any man ever and he knows that but I’m just wondering if there’s truth to what he says or why he says it. He’s way more to handle than I am that I know, but is it just a way to hurt me or is it actually what he’s thinking about? We’ve only been married like 3 months yet he says Marriage is forever! lmao He was pretty much a confirmed bachelor before me he’s in his 30’s me mid 20’s....
