Im not sorry. However, I personally like to know wat my guy thinks. If he likes me with long hair rather than short than I will gladly learn to style my hair better and keep it healthier to see his enjoyment.
I would definitely talk to him and let him know that I'm thinking of it. It's my hair, and the final choice lies with me however I think that changing your look in such a major way will take time for you BOTH to grow used to. I'd talk to him, but asking for permission is a bit much.
