Hi Wishing. I totally agree with BM. We had the same discussion in front of our C, in fact she brought it up. She said that it is damaging for the kids to meet someone the parent is dating, unless it is going to be a committed relationship, and even then who knows. The theory is that they feel like people come and go and they get abandonment issues. There is a lot of research on it, but if presented by a C it is probably a lot better received. My 2 cents for what it's worth.
