He's lovely, but he comes over practically everyday after school, my DS is 10 and he is 8 and really likes my DS. My DS likes to play with him, but not everyday and even at the weekend. He has a younger sister, the Mum never comes with him and he looks so heartbroken when I say not tonight as my DS does not want too. His Mum is Spanish and lovley, but very laid back which is great, but the whole language thing is tricky as I have spoken to her about it, but it did not seem to go in! I feel sorry for him telling him no but he's not mine! What to do?
