Haha You're Still Single

Valentines Day.

A day for me to watch and reflect on the world that has passed by; friends and relatives older than me already married, engaged, or at least in some stable relationship.

Those younger or about my age, and many of which, very recently, have found partners. These couples seem to be sprouting like mushrooms after rain; so sudden and in large numbers.

And then there's me. Still the same ever since I was born.

One time, I had put in genuine effort in a girl and she ended up liking somebody else (not that anything even managed to start between us).

One girl that I have liked for a while and have known for much much longer, didnt feel the chemistry.

And then there's the rest of them who:

 Look like the type I'd want to know better

Or

 Have known for a while or fairly close, would want to try and see if something works

but:

1) Barely reply

2) Are always busy (may go together with #1)

3) Are already eyeing someone else

4) Are already WITH someone else 

5) Gives the friend/brozone

6) Are leaving the country

This may make me look like a player by trying to get more than one girl, but then given my 0% progress rate thus far I dont think I can even be a player in the first place.

Am I missing or lacking something important?
Am I making the wrong approach?
Is life playing one big troll game with me?

Answers are needed.
