Why answering seriously to someone who's clearly fucking with you?
Seriously speaking, marriages aren't a bad deal overall, being a mother is A TON of unpaid labor that falls sqarely on women's shoulders so it's just fair they rob you blind when separating. Sucks to be in that situation but it's reaping what we've sown as a society.
What sucks is you didn't choose these rules and neither did I, and of course if I had a say it'd be different.
Most people just suck as relationships, will commit to a shitty one for fear of staying alone, or will lie and pretend to be someone they're not just to fuck and once you're living in a house together all the shit comes up and escalates. And this is true now as it was yesterday, just yesterday we were forced to stay in shit relationships that sucked our souls and happiness for a lifetime.
This doesn't mean that it has to be like this. Love isn't with a person but with a way of being together and a number of practices, habits and feelings. It's something you build and it requires intentional effort all the way through. It's hard but no one forces you to marry.
