My boyfriend has two kids I love every much. They're from two different moms... The first child is a boy he is 6, he is a great kid, very smart. His mother is an addict and my boyfriend has full custody of his son, and we have decided to keep her out of his life since she kept seeing him then doesn't call him for months off and on, even forgot his birthday. His son doesn't even call her mom. He calls me mom, so it's not much of a problem. He also is recently divorced and has a second child. She's almost 3, she's very great with speech, follows her brother around, loves me as well, potty training as we speak. Her mom completely hates me and hasn't even gotten the time to know me. First day I met her she tried to hit my boyfriends car with her child in the car and said she was worried about who her daughter is around but not about her safety? Also they finally went through court and we have 50/50. So less problems, but the crazy mother is still doing her thing. I try to ignore it until she makes it my problem calling my boyfriend all the time. It's out of hand. How do I get her to stop thinking she's his problem still? She's 22. I'm 26 I feel it won't ever change but I need it to. We will argue because of her. It's just gone to far with her. Also my boyfriend treats his kids differently. His boy get into trouble and I give him the motherly he hasn't have. I love him to death. He has zero relationship with his dad. I hate it, It hurts me to see how different he treats his son then his daughter. He babies his daughter too much. I try to explain to him and we get in arguments because he's always sticking up for her when she's on trouble. I understand they're different in age and don't exactly get the same discipline but they do need to both be disciplined and they both need to be treated the same. He doesn't even look at his son the same way as his daughter it sorta sickens me. I don't know what to do. How do I change this? It's almost like he looks at his son and sees his mother which is no where near fair. Please help me.He also thinks because she's a girl she doesn't get in trouble as much as him and that it's ok she's babied. When if he babies her she's always going to act like a baby, it's best to break it now then later or she's always going to be depending on him. He just yells at his son all the time.
