I am kinda sad the way my daughter acted to her dad yesterday I just sad for her. He doesn't see her in like 3 weeks and he come over yesterday to come see her and all she did was cry but when he gave her back to me she stopped 😢 i know this is his fault but it breaks my heart! She is going to be going with him Sunday for 5 hours I hope she does okay....
