I met a friend of a Friend briefly (call her X), where we only exchanged names and not much else. Later I added her on Facebook and asked both my Friend and X if they wanted to get dinner that Friday. Friend is down.

X: I'm open to that, I'll be meeting Friend tonight so we'll talk about it then

But after they met, Friend told me she's busy, and dinner got cancelled. So I asked X if she wanted to get coffee over Facebook. No reply.

Now, I've learned a ton from seddit, and as we say, we move on. I'm pursuing a couple others as we speak, but this one really stood out to me. Is there anything I can do at this point without seeming like a total creep?
