No, an apology doesn't make it all right. In addition, he has made repeated, graphic, verbal threats against your life. It is not unusual for this type of violence to spill over onto the children. Often abusers will delight in doing everything possible to cause problems by using the child. In some cases, abusers will make threats against the kids, kidnap them, and in rare cases, actually kill the children and commit suicide.
Abusers often abuse the children, whether it is 'only' verbally and emotionally, or physically.
This type of abuse will have long lasting effect on a child, perhaps lifetime effects. Abusers need to release the anger inside them and if no one else is around, a child will do. The fact that the abuse wasn't directed at your daughter is irrelevant. The anger that drives him wasn't really directed at you, either. Although he may have come up with some reason for exploding at you, it wasn't personal.
