How many times do you put up with your kid beating up his mother when he comes home drunk in the middle of the night before you require him to move out of the house? Keep in mind that his is 15 years old...

As parents, we tend to believe that we will always love our kids in a way that allows us to maintain healthy functioning relationship with them no matter what happens.

But when you see what can go wrong in families and how 1 member's behaviours can have a massive detrimental impact on the other members, you realise that there are limits to that.

While I will always love my kids, I know, objectively, that there are circumstances that could force me to fundamentally alter the terms of my relationship with them. I pray that never happens, but I know it's possible.

Similarly, I know plenty of people who no longer have any relationship with one or both of their parents due to the way they were treated as kids. Society (rightly) tends to be more accepting of a child who decides to sever their relationship with an unloving parent than the reverse.
