My husband (41M) always tells me (27F) that nobody else would want me if we divorce.

When we fight and talk about separating, he tells me that nobody else would want me. My husband and I love each other and I know he just say that cause we’re fighting but sometimes it does really hurt me and makes me feel ugly. He does say sorry after but I don’t respond to him cause I’m still hurting then he would tell me quit being a bitch. Sorry this sounds more like a rant than asking for an advice. Sometimes I do feel stuck cause he might be right, nobody else would want me. We have a son too and I don’t want him to grow up in a broken family. My husband and I both have broken families if that matters.
