That's why I say how u treat her is going to leave a big impact on her. U don listen to her likes and don likes. U keep wanting her to accept ur relationship. Since u don understand her so she choose to ignore u. That is normal for her to react that way. She must be thinking that u rather wan that man and don wan her. Kids are very sensitive. Do u wan her to continue to grow with weird behavior and character? This is the harm that u had brought upon ur own daughter. She don have a father ald and I think u love urself more than her. She is really pitiful........she seems to be a bit rebellious nowadays, both of us cant really communicate well, always moody, after class or tuition, straight away inside her room whole day even thou he not around, is she something wrong, hormone changes or ? , she just 9 years old only.
