Very mysterious advice, thank you abbott.
I am not going for him at this time.
Things are weird, it turns out we have several mutual friends, and things in common that are uncommon. Also, turns out he dated a friend of mine for a few years, and before that she had dated a suitor I had previously rejected. And our exes are friends who play music together. Adds a very dense layer to the acquaintanceship.
Long story short, I now believe this man is my son, sent back from the future to kill me. So I'm going to try to work harder on developing my current relationship instead.
