She can insult everybody including me.she can be very loving but very disrespectful when upset.i am not happy with her at all.what do i do?

Try to adapt to that . . Marriage is for better for worse;afterall, you must have noticed all that when you guys were still courting.

Do not condemn her and try to be more loving. Also, when she is calm down, let her know how you feel about her continuous outburst each time she gets angry. I think it is something she should be able to control if she wants to.

She didn't just develop this traits over night. She would have started it while you guys were dating.

That's always the problem, little things like this were meant to have been discussed and sorted out before marriage. But people will be screaming "I love him/ I love her".

You can't do anything about it, cause you can't only caution people, you can't change them.

Just pray she doesn't insult you in a family or friend's gathering on day.

And note; Physically assaulting her won't change anything, it will only make things worse so don't go that path.

Keep letting her know you love, care and adore her but want to be more polite and calm. That could change her a great deal.
