OP, so he’s said more than this? What else has he said?
My brother is like this, he sends the most horrendous abusive texts when he is stressed or angry then expects me to carry on as normal as if nothing has happened. Dad was the same. Same type of men. It is emotional abuse and it has affected me my whole life and I don’t live with them.
You are being asked to accept this in your own household day in day out. Please don’t. He is showing you what your life will be like and as others have said once you have children you will be far more stuck than just having a house to sell. Dont settle for this, it is abuse.
Run, at the very least tell your friends and family and really look and listen to their reaction. It is not normal nor is it acceptable. Better cancelling a wedding now, no matter how awkward it will be, than walking out 10 years from now browbeaten with children in tow, fighting him over custody.
If he feels safe enough wishing you dead now when you are only engaged to him, what will be like when you are married? This is real red flag time.
This is not normal, you know that.
My husband of many decades would never behave like this. Please don’t accept this or listen to excuses from him as it will happen again and again. It’s part of him.
