I love my son more than anything but it gets really tiring when he wont go to sleep, refuses to sleep in his own bed, is so cranky all day and his father isn't around to help ever. But it's ok because I got this. I'll always be a much better mother than he is a father and this is my first time and his 3rd! and he doesn't give two flying fucks about this baby all he cares about is himself and his daughters, and it's really really starting to piss me off where idk how much longer I can keep my mouth shut from flipping out on the piece of shit! 😡 I hate him I really fucking do. He's a narcissistic, ruthless asshole and I'm done dealing with it. I've tried to be the bigger better person and idk how much longer I can bite my tongue. 😒
