I Am In a Difficult Marriage

Your story is very sad, 3 months into any relationship is a very short time to have gotten married, but when you fall in love the height is very high and the fall is very hard. If you had given more time before getting married, maybe you would have seen this side of her and they are red flags.
Love should be unconditional and forgiveness is definitely a part of that, but love should never equate to abuse (Physically or verbally), disrespect, anxiety, stress or even fear of what might trigger her to have her outburst of anger. People make the mistake in hoping or wishing that their partners would change, you shouldn't try to change her; she has to do that herself to make it a lasting change. You can propose to her to go to marriage counselling, so she can recognise her faults and change. Unfortunately you have to be hard and brutally honest about your own thoughts and feelings, being gentle and meek will not prompt her to act. You have become her security blanket and she knows if she apologised sincerely enough you will forgive her. She is putting a band-aid fix to a gapping wound. But the fact is apologies means they won't repeat it again or try their hardest to not repeat, other wise "Sorry", becomes just another word it's hollow in it's meaning and you lose your faith in that word too. It sounds like your still in love with her and you must give her an ultimatum if she wants to save or salvage whats left of your marriage, she must swallow her pride and meet you half way in counselling. Remember Love means- compromising, balance, respect, nurturing and supporting.You must think of your own sanity, self-respect and your health, drinking trying to drown out the situation can only worsen things for you and her. You are not in a inapt situation, be brave and remain true to yourself any human being deserves to be happy...why not you! You can only try your best in any situation.
If you have exhausted every thought and resources, at least if there is no result in all your endeavours you can walk away without any regrets. Best wishes.....

I agree Both of you need to seek help if you want to stay in this relationship

Well it was only three months before marriage but maybe she was hiding her other side until the wedding day and then was she was comfortable the other side came out. I have a friend which that happened to and that marriage lasted 7 months before it was off to divorce court. Yes marriage is suppose to be for better or worse sickness and health. Well if people hide a side that's unfair. People have faults this is a way of life the question is can you live with those faults and their are some fault no one should live with and that is abuse either physical or verbal.

Maybe you need some time apart (hang on I forgot to put my disclaimer on - all advice is given in good faith and I must point out I have no 'professional' training whatsoever although I have lived through a lot of sh*t, a lot). I'd also ask her why she blows up

It sounds like she needs psychiatric help as well as medication. That behavior is completely unacceptable especially if you have children.

I feel for you. Life is short and we should be happy. Maybe if you go to counseling she will join in at a later date.

You both need to seek for theraphy. She is dragging you with her and there is no way you alone can help her break this cycle.
Don't be afraid to seek for help. This is clearly escalating quickly and things could get way worse.
