Re: Mother’s day (mother in law)
How does her family handle Mothers’ Day? Do her children acknowledge it and give her flowers, etc.? If yes, then you should stick to your original plan and send her whatever you think is best. If this isn’t the norm in their family, then just send something later and call her instead for now.
All these ‘she has no relation to you right now’ advices are disturbing. Going with that logic, the guy has no relation to you right now either. Did you still expect something on your birthday and/or valentine’s day?
