I feel your pain. I went to a woman for a long time because she was nice and my sister went to her. One day, BAM! Mullet! That's right. I had a mullet, as a female adult. I also have red hair, just to pain the picture a little better. This was about 4 years ago.
My best advice is to learn the best way to put your hair up to hide the haircut. For my mullet, a ponytail pretty much just exaggerated my short-bowl-cut front. I ended up using a lot of bobby pins and headbands.
My boyfriend at the time never said he hated it, but never said he liked it. Years later, I talked about the mullet and he sighed with relief and let it all out

What a trooper.
