DS is 7, I was with my ex for 3 years and he has a 14 year old son. He moved in with us so we saw a lot of his son, and DS was close to him.
In May, I worked a night shift and his ex’s was over that night so ex was home alone with DS, and his son. When I got back the next day, DS was very quiet, in the end he told me he heard ex shouting at his son and then he saw him grab his arm and he wouldn't let go, until DS told him to stop (ex didn't think DS was downstairs). As soon as DS told me this I split up with my ex and I told his sons mum. She was grateful, and I don't think he sees ex now.
Recently, DS has been mentioning him and says he misses him and wants to play Minecraft with him etc.
Wibu to ask his mum if DS can see her son?
