M16 F16 is it weird that my mom keeps making comments about my past relationship?

I’ll show her a picture of the new girl i’m seeing, she says “uhhhh i liked [ex gf] better”. Just unusual comments all the time. She said the other day when we were somewhere “i bet you wish [ex gf] was here, too bad you broke up” like yeah dude thanks for reminding me. My mom was buying me food the other day too and said something like “i bet you don’t miss this food as much as you miss [ex gf]”. I want to know if this is weird or inappropriate or if i’m just seeing this wrong.
