My Crushes Mom Keeps Asking Me M18 To Marry Her Daughter F17

I am M18 doing college online while working full time. The person I like is F17 and still in high school. My parents are very good friends with her parents, so our families are together a lot but she is rarely with them.

Almost every time I am around her family her mom always call me son-in-law or calls her my future wife. She also says other stuff like that, but you get the idea. I am not mad at her for it but I do get embarrassed. She never says stuff like this when the daughter is around, but she is very busy so she usually isn’t.

I have liked her for over a year, but we are both shy and have only said hello to each other a couple times. I also think her mom saying stuff kinda makes it more embarrassing if I try to talk to her.

If anyone has advice for this situation please share.
