My MIL kissed the back of my neck.
Today i was hosting a birthday party for DD2 and had invited MIL because it's the right thing to do (not because I wanted her there).
When MIL arrived she completely ignored me - for the whole party barely more the 5 words were exchanged between us! (great, no complaints from me) however, as she was leaving I had my DD on my lap and so couldn't easily get up to say good bye, so she comes from my behind and plants a slobbery kiss on the back of my neck. There was nothing to stop her coming around to my front to say bye.
I was never felt more cringed or violated in my life. It doesn't help that I really detest the woman. My DH said he saw the whole exchange and thought it was very weird.
How should I handle that in future? I never want to be in that situation again
