My sister in law has started going out with a new guy. My 3 year old daughter has only met him about 3 times and I've always found him to be a bit intense with her. He doesn't have children but is very hands on with my sister in laws child. When saying goodbye to my daughter when we last saw them he tried to kiss her on the lips. She reacted uncomfortably and turned her head so he kissed her on the cheek. But then he tried again. Again she turned her head and tried to get away. I was so shocked that I didn't fully process this and did not say something at the time, which I now hugely regret. Am I being unreasonable to this is seriously inappropriate behaviour?? Would anyone have any advice on what I could do now so he does not do that again. I feel like texting my sister in law now may lead to too much tension or an argument.
