Agreed. There isn't a real point to suppresing that side of you anymore and trying to over compensate for it. The more you try, the more depressed you are probably going to feel about it. I do hope you can work that out with her though, it can be a big strain on relationships just due to other peoples viewpoints and personal feelings. I guess what I would do is try to explain yourself, that this more than likely will not pass for you, and just try to get her to see with you on level that your sure in yourself. The sad thing is, it may not be enough, but you did try!
Anyway, agreed with the Elf one. Hope it works out
