I’ve chosen to be proactive and make every attempt to prevent those crushed feelings from being my own.
Most cases where a new relationship starts up, a friendship changes (for better or worse), or a friendship turns into a relationship, are often preceded by some sort of life change.
My guess is that one or both of you are at some kind of crossroad in your lives.
A: That was so hard to do because I wanted to date you!
B: You always gave me good advice when I was dating her.
Of course, being official or unofficial are just words, and ultimately titles don’t make relationships…but commitments do.
