I’ve known FIL for the last 15ish years. He is 75. He has been a thorough gentleman all through. Inlaws live in the US, we visit them every year. MIL passed away a couple of years ago in a sudden accident. Ever since FIL has been visiting us more often and at times staying for 2-3 months at a time. We stuck a friendship during his recent visits. We talk about politics, astronomy (is was a professor) and yoga (my passion). I see him as a father figure and a friend. DH works in a hospital and I work from home. I take FIL out and about with me - grocery, school runs etc
He has been acting weird lately. Pinching my cheeks, Putting his hands on my shoulder, and yesterday on my waist. WTF !! I was totally taken back and he doesn’t seem to realise. He was never a “creep” IYKWIM. But this touchy behaviour is making me very uncomfortable. I don’t know how to tell him to stop without ruining our friendship.
