Father-In-Law kissing my neck?

Hi everyone.

recently my father-in-law has started to quickly but noticeably kiss my neck during a hug. The hug being either like a thankyou or a I’m proud type hug. He’s never kissed me before ever and it seems strange to me that it’s on the neck and not the cheek as I’ve only even been kissed on the neck by my husband and for other kinda reasons.
My FIL is (55 male) I’m (20 female).

what’s your thoughts? I really need them !!!
Ps. I have also told my husband he’s aware but doesn’t know how he feels (he believes it’s friendly ness but he doesn’t seem sure just not saying it)
