He’s 8 ans told me hw doesn’t like me as he loves his mum. I’ve always been kind and included him and try to have him bond with our two year old, when we are alone he tells me hw wants his mum and dad back got her (they was one when they split up) he tells us he hates his step because he wants to share his mums bed again. He cries a lot and lately he’s been talking about sex making noises and saying his mums name whist making these noises he even told us he imagines his mum having sex, his dad just doesn’t say anything so I kind of leave it because last time i said it’s not right it caused a argument.
