<human>: Can you provide a brief overview of the text?

I apologize for the vague title, but here's the story: We have been married for three years now, and we have never had a time when we were just good. As the title reads, this is mostly my fault. The reason I know it is mostly my fault is because I started our marriage thinking I could change myself into what she wants. She really is a wonderful woman, which is why I came to the conclusion that I needed to change who I was at my core to make her happy. Well let me tell you, ladies and gentlemen, that does not work. So our relationship began on a foundation of lies from me, which inevitably lead to many fights. And our fight are BRUTAL (swearing, name calling, finger pointing, etc) and can last for weeks. Now she wants a baby..... 

Now, here's my problem: I want out. We are so different in every aspect of our lives that we can no longer enjoy each others company. But there are a few reasons I haven't and may never leave. First, our families are an issue. I am so close to hers, and she to mine that they would be devastated. We do a lot with them, and I can not imagine hurting them in this way. But my biggest hesitation is that I feel like I will have robber her of most of her prime years. If I leave her, she will not be able to have kids. It's difficult to explain, but basically she has a debilitating disease that requires very potent medication which may cause harm to an unborn fetus. So we have to plan this for many many months before we can start trying. And I don't want to rob her of the joy of having kids. And the last thing is that we just built a very expensive home that we have been in for less than a year. So financially speaking, this wouldn't be the smartest decision (no other debt except my motorcycle)

However, we are utterly miserable. We can't sit through a single dinner without fighting about something. And as for what we want in life, we are totally different. I like white, she wants black, etc. I don't know what to do, or where to go for help. Any suggestions?
<bot>: I have messed up a lot and I am the one that wants out, but for many reasons I don't know if I should.
