Mother's Day note for girlfriend's mom?

koopa22
Does it seem alright for me to send a handwritten note to my girlfriend's mom on mother's day? I've met her many times before, she tells my girlfriend how much she likes me as a person, and definitely cares about me. I just want to tell her I appreciate how she raised her daughter and that she should be proud because I truly feel this way. Is it okay to send something like this for mother's day, or do mother's only want things from their own children?

I would start it out with explaining that I realize she isn't my mother but I appreciate how good of a mother she was to my girlfriend.
