My boyfriend was drunk and threatened me by texting.

If he does this every time he drinks, I suggest you think carefully. It's not about the wine, it's about his emotional management. As you can guess, there may be violent tendencies after marriage. Many marital violence can't control emotions, emotions are out of control, and violence occurs; When you are awake, you will regret and apologize; But it's no use. So repeatedly.

In addition, this person is extremely insecure and has poor emotional management skills. Leave before it's too late.
