I hate that my ex lies to me! I know he is just lying out of his ass when he tells me my son sleeps from 730pm to 7am without a single peep. That's bullshit. The other night he went to bed between 9-10 and slept till like 430 and then I laid him back down and he slept till like 645. And even when he's gone to bed later like 10:30 cause he's been sick and struggling at night he's still up at 4:30 and then is all over sleeping with me till like 7:30. He's a liar! He lies about everything and it's not right. I'm the primary parent! I need to know what's going on with him. I'm always always honest with him about what's going on so he can take care of him properly or so I hope. Ugh! Anyone else have this issue?!😠
