She just said 'that's what makes you who you are, I've never thought of you as a bokey bloke anyway'. She asked a few questions which I did my best to answer, then we had a hug and enjoyed the rest of the day. I'm keeping everything the same, giving her time and letting her be the one to raise the subject rather than me, but I'm just so amazed at her reaction and relieved that I have finally been honest with her.
PS I took down my avatar in case she looks at the site, she should only see me when she's ready. That might be never, but that's fine with me.
