I have a new family in my care, and the dad does almost all pick ups and drop offs. I find that he's becoming very...familiar with me. For example, he will stand in the door and just kind of stare at me, or make awkward small talk even after his kids have run out the door and are in the car waiting for him. I have started to just walk away, pretending I have something on the stove, or that one of my kids is calling me from upstairs. It feels weird, but I can't say that he's really doing anything weird that I can put my finger on.

Anyway, his son has become friends with my son. They're 9 and almost 9. The dad texts me about son coming over to play, or my son going there, etc., so there really is a reason to text outside of daycare hours. BUT - he sent me over 30 texts this weekend. Most is chit chat, but some is weird, like, he sent a text to me implying sexy things and then claimed that he meant to send them to his wife.

Last night, he mentioned casually that he'd be half an hour early this am, and I was sort of annoyed. I said, "well I'm glad you told me because I would have still been upstairs and not ready when you got here." He replied with, "Oh, well I wouldn't want to catch you undressed", and then a winky smiley, which kind of grossed me out, to be honest. I mentioned it to my DH, and he's not at all impressed. He feels that the dad is crossing a line.

I am uncomfortable. How do I nip this in the bud without insulting or losing the family? I really like the kids and the mom, and I honestly can't afford another family lost. Any advice would be fantastic.
