Losing my mind with my whole situation! My mother is living with us, my boyfriend is constantly trash talking her to me, and I see where he is coming from with his frustration but I don't care how much she angers him, she's still my mother! Plus our son is 2 months old and my boyfriend has barely helped with him at all so now the baby wants nothing to do with him, and everyone leaves everything up to me! this mommy is going to start going snakey on everyone!
