Husband jokingly threatened that he’d kill me

Several months ago my husband stated that he’d kill me and the hypothetical man I’d cheat on if I ever did so (I’ve never cheated). He played it off as a joke, but I understood the veiled threat. I confided in my friend about it..she said to not take it too seriously. I later told my therapist..she found it strange and a bit alarming. I did eventually confront him about it. He acted as though I was being paranoid and said it was only a joke. Ever since he has yet to make a threat like that.

Is that all it takes though? One threat? It’s made me uneasy ever since. I’ve thought about confiding in my mom about it, because I trust her. But there’s no going back after that if I do. I can’t tell my family that my husband made a threat. I’m afraid of what that’ll do. I’m not financially stable on my own yet. I don’t know if I’m just overreacting.

Since then, I’ve lost a lot a trust in him. I don’t want sex with him. He’ll back off for long periods of time, but then once he feels it’s been long enough he’ll push me for sex until I feel like I don’t have any other option. He hasn’t been physically aggressive otherwise, but will use his good behavior. Or treat me wonderfully. But then he’ll slip up and call me a b**** completely unwarranted.

It’s all very confusing behavior. My mind literally gets into a fog. I’m just confused on what to believe anymore.
