Leave. You are, in fact, destined for a lifetime of domestic violence if you stay.

Just because it has been a while doesn't mean you have lost your window of opportunity. It doesn't MATTER how long it has been. It will happen again, and the frequency with increase. There is no limit on how long you have to leave after he did it before your decision becomes invalid.

It isn't your fault or responsibility if he doesn't know what to do without you because all his hopes and dreams included you... He punched you in the face... That was HIS choice. Being drunk doesn't excuse it. Being stressed doesn't excuse it. Assaulting other people is not OK. When he cries and blabbers about his hopes and dreams it is just manipulation and guilt tripping.

Leave. Save yourself. Good luck. HUG
