So i (f) have two step children one 14(m)one 10(f) years of age that live part time with me and my partner(m) and part time with the mother. My partner and the mother spilt about 5/6 years ago and I know that it took a lot for them to get over that. We have recently told them both that we are expecting a new baby(in oct 6 months away). The 14 year old is very excited to have another sibling. On the other hand the 10 year old has taken the new really badly and has shut herself in her bedroom. Before this me and my step daughter would spend quite a lot of time together. She is now refusing to even be in the same room as me. Which I understand, won’t come out of her room when she’s here and will beerly speak to her farther, My partner her farther has tried to speak to her about it but just keeps hitting a wall of I don’t want to speak about it. He has also tried leaving the conversation alone for a few days to see if that would help. But nothing. My partner feels torn between us as he doesn’t want to just leave me on my own while he tries to spend time with her(which I’ve said is fine, do as you need. Honestly don’t mind) it’s making home life a little stressful at the moment. I tried spending time out the house to give her space, however even when I’m not here she won’t leave her room. Anyone got any advice or been in a similar situation?
