My 6 year old son sees his father at least once a week, for variable amounts of time. A new partner has came on the scene and they now spend all the time at her house. My son came home today and told me he spent all his time downstairs watching tv in his own whilst dad and partner were upstairs. DS tried to go upstairs after a while as he was lonely and needed a drink and couldn’t reach the tap. Dad shouted don’t come up here, go away and they didn’t come down for a long time after. I can take a wild guess what they were up to.
I don’t know what to do. I think he will just deny it if I say anything and I don’t think is acceptable. I’m sad for my son and don’t know how to proceed.
