What do you do when you realise you are married to someone who has a temper?

That sounds like domestic abuse to me

i guess you cannot do anything because you are already married

Alot of women r in the same boat as you are and all i have to say is you cannot put up with any kind of abuse whether it be physical or verbal we are not put on this earth to be terrorized if i were you i would talk to him about if you can't then to must talkto someone i was in an abusive relationship once and i never kept it a secret i told everybody in my family u shouldn't be the one who feels embarrassed it should be your partner who feels that way anyway when i told my family what happened one of my older brothers put a hurtin on him, and my mother wanted me to come home again to catch my bearings and to get my strength back i did tell your family u need all the support you can handle please don't stay to be somebodies lapdog you are to important

if he finds out what? I think that you may want to see if he has had an anger management OR if perhaps he is on any medication. Sometimes if he was taking medication or something and got off it, that can cause some of the haywire in the brain to begin. Has he been violent?
