Unfortunately, my situation has so many other twists and turns that I doubt I'll be a good baseline for you or others here.
Here's why:
I was previously married and had two boys. She sees my ex, who I had a good working relationship with as the enemy.
She uses my boys as ammo against me when she has an episode. They're "the worst thing to ever happen to us. They're stupid. They're awful. I hate them. Our life would be so much better without them. They're a mistake." I can not count how many times I've heard this. She know the power those words have on me.
I asked her to marry me after just two months together. We were married in a week. Within a week she was threatening divorce and I had a nervous breakdown, thus ending up in the hospital. A couple of months later we're pregnant (her first) and I'm told to either pick her or the boys. Instead I attempted suicide and obviously failed. Back in the hospital.
I am now in a legal fight with my ex over the boys. She has a restraining order in place saying she can not be around them. My wife has never said the things to them nor threatened them, but the info got back to my ex. So now my ex is basically making me choose.
I have lost the support of my friends, my family, and my own parents. It is now her and I against the world.
Yet through all of this, I love her more than I've ever loved anyone. I've learned to better handle the outbursts and fully understand that she does not often mean the things she attacks me for. I also know that I am probably not the most stable person for this relationship either (manic depression and fears of abandonment). Still, I would go to war with and for her and given the chance I would do it all over again (with maybe some different way of handling things). The bad has been disgustingly bad, I will not sugarcoat it. BUT, the bad has only been a small fraction of our life. The good has been better than anything else I've ever been involved with. Plus I'm happy rto be having a baby girl.
i know this reads like a bad soap opera, and that's why I've tried to say I'm probably not the best example to go off of. Don't rush into anything and read, research, read, and research some more. Don't ever stop asking advice or questions from others. But more importantly, be happy and confident in your decision.
