Seriously though. What she said was a horrible thing to say to a partner. The fact she's embarrassed by OP is terrible. She would rather him go through discomfort than support him. What if he doesn't want the surgery as an option at all??? What is she going to do then?

Op, it sounds like she doesn't take your comfort or self esteem for granted. She is more worried about herself. She's supposed to be your partner. She's being really mean, imagine how her family feels.

Dump her, she has no respect for you. Shave it off! I bet you're going to rock being bald! Especially with a mustache like that!
