You seem like a really lovely person and I wish you all the very best.
My daughter is my best friend (apart from my partner), so I know how much of a struggle stepping back from that relationship is especially when you're going through new things that are both challenging and wonderful. You want to share and I used to share just about everything with her. I suppose in a way I have replaced parts of my relationship with her right here on this forum. We still have a great relationship but as I can't talk about such a significant part of my life with her it isn't what it was.
You are in an even more difficult position because your love doesn't live with you, so why don't you start a blog in the blog and life story section. Just share with us how things are going, your achievements and challenges. I for one am very interested to know how you go.
