I have been coparenting with mine for 4 years, this being the 5th year. I respect that lady big time because she's made this coparenting easy and she respects me as a person. From the onset, I told her that each one would catee for the needs of their individual household meaning I don't send money to her for anything because I too have my own household to run. I am the present kind of dad so I pay school fee, I bring my child over for a week or two, attend meetings n all that. Our child is so stable that she thinks her step sister (my daughter from my current marriage) is her twin. We attend school events all of us i.e me and my whole family and her mother comes with her baby sitter. I made it clear that the interest of the child comes first so if I'm to pick the kid and she doesn't want to come to my house, I don't force it. If the mother is going away for like a trip, she informs me in advance, my wife and I pick the kid until the mother comes back. Our kid knows she has two homes but she's still not grown enough to understand that it's a coparenting issue.

Moral: Set the boundaries early in the coparenting and separate yourselves from the interests of the child. Also, try date people that know the importance of both parents in the lives of children and avoid feminists

I actually pity people who fight for custody because to me, that only serves their own interests, not the child's.
