So, she has lost a lot of weight, which is amazing for her and hope she keeps it up.
But as everyone knows what happens when someone loses a lot of weight, I'll let you envision that.
I do agree she looks great, but if that is not something that you can overcome then I suggest you not seeing her.
I say that more as, if you don't like it and you inadvertently say something negative, it could be a hindering to her, which we all don't want that.
Best of luck, if you choose to go see her.
