So the child can, instead, grow up in a home with a raging cunt bitching at you all the time; which (if I have to guess) you don't just take without a word and argue back? Sounds like a lot less healthy of a home to me.
**This is just a judgment of how the situation sounds as you described in this thread and may not be like this at all. But, I don't think it is going to work with any woman you think of as a "raging cunt" as there is obviously no respect in the relationship. However, good luck with everything.
