Indeed this entire thread is - why there are subs like r/childfree. People that become parents can be many things.

When it goes sour like this - it get's really ugly really quickly.

No one wins in a long drawn out court case - $1000s are spent on shit basically. No one wins with clunky child support arrangements that punish Dads and encourage them to work their arse off to see them intermittently.

Solo Mums get real tired, and honestly do their best but want to remarry/new boyfriend as soon as possible and we all have questions and hear horror stories about the new drop kick that Mom gets in her life. Mom's are just caught short with this whole deal. They get to play the victim card. It gets really old. Men "sux right?" Sure - right ok silly tart.

Dad of course has no real incentive to do well with his job. If he looses it, well he pays less child support right? So causal - under the table work can pay for his needs so long as the car is cool and he can continue shagging whom ever will have him in the 2nd hand divorce market. Dad's of course feel dead inside as it's easy to blame everyone else for what happened to him drink a few few beers and call women bitches right? Because it's not his fault - when to an extent it was.

Then there is the kid experience. You wind up hating your parents equally they both are pathetic. The "looser" for just not doing enough and the "winner" for being so overbearing. The walking around on egg shells, being blamed for shit you didn't do, it never ends. Birthdays are ruined forever, and you are begging from one "adult" to another for resources and things you need.

Basically - when it goes pear shaped it goes pear shaped.
