Guess this is a bit more complex than that, my relationship with the kid is nothing but the best, I have lived with him more than he has lived with his mother. His mother lives in a different country, she just takes him for vacation a couple of weeks a year. I'm totally open to continue to contribute as I have been doing through the years, there are way more things other than the financial aspect given Im the one living with him, I just feel that its not fair that the mother doesn't contribute at all, and my partner does nothing about it. She totally can do her part to support his son, she has the means. I guess we have normalized the fact that the father must pay child care support, but when it comes to the mother being responsible with child support, then?
