Hello Jamelia and welcome to a2k
If it were me, I would not write an email back. You've made the first
move, he responded late and hasn't dropped you a line since. He seems
very nonchalant about it, so I would assume, he's got too many fires
in the oven and can't handle more.
I don't know how this works, so I have to ask: when you see the profile
of your "suitors" do you see their pictures too and vice versa, do they
see your picture?
