Have recently deactivated Facebook to get away from the temptation of messaging someone. For background, we spent time together for a few months (non-romantically) and I felt an immediate spark, it was indescribable. No idea if the feeling was mutual and I never mentioned it, I haven't seen the guilty party for a few weeks and thought said feelings would subside, they haven't. Am constantly tempted to message or email but I don't.
When we first met I noticed that their body language was different towards me, it was inviting and open, as if they maybe felt the same. In my idiocy I must have seemed cold and non-responsive, because I was so convinced they would be horrified if they know, and eventually they changed towards me and sort of cut me out. So again my idiotic response has been to avoid messaging and speaking to them, even though I desperately want to. Realistically I know it wouldn't work. But the feelings won't go. 

I'm a twat. Send help.
