DR Vixter, I have a very good memory of what it was like in high school & the confusing mix of relationships between guy & gal friends. This adds a new, more difficult, dimension to the usual situation. OK, from experience….You can stay best friends with someone you really like, even though it hurts at times, not date and stay friends forever & be glad you never dated. You can date your close friend, not have it work, and still stay friends. It might not be the same friendship after so it is a risk. Last & best scenario (Keith’s & mine), you begin dating your best friend when you are both 17 and it lasts forever. Not easy to do at all & the statistics are against you.
You seem to know the secret the best friend didn’t share. I find that odd she hasn’t & does the one friend know she has been kept out of an important secret? Not knowing the secret I have no idea how that info might tip the scale. Secrets are not a good beginning for a relationship & they both seem to have one.
My advice is both these girls need to be older & really figure out who they are. If the one friend is as close to her mother as you say, what did her mother suggest?
