No, No, No, No, No!!! I can understand why some couples think it is better, but it really isn't. Staying in a bad relationship or any relationship where you aren't happy is just gonna make you miserable. And this will have an effect on your children. They need two "happy" parents and given out society today, that is okay.
I was with my sons father for 8 years. I went through awful mental and physical abuse for all of those years because I thought it was best for my son. That is not the truth, it is just something that we think is best because of how families are "supposed to be."
All you have to do is make sure you gave it a good shot and there really is no other way to be happy except divorce. In the end, your chidlren wil thank you for it.
Absolutely not!!! Your children will grow up with similar relationships as they see between their parents. I wanted more for my kids so I left and never looked back...it's not easy on anyone but kids are resilient. Good Luck!!!
