<human>: Ok, so I suck at talking with women, and I suck even more at telling whether or not they are interested in me.

I have, for the most part, been a fat kid/guy. I weighed 230-250 lbs from the time I was 14 up until just last year.I was never a super mack, but I did have a few GF's in middle school. The first chick I ever dated broke up with me 2 weeks later, exclaiming she only dated me because she felt sorry for me.  In highschool, I asked chicks out that I was interested in, but all were the same, "i think we are better as friends". 
 I've had a few decent relationships since then, and a few not so decent. I haven't dated anyone in over 2 years, and I'm not the type of person who can pull off a 1 nighter.. I dunno, it just seems nasty to me... If I can get this chick to fuck me that fast, how many other folks have run up in it??  
Now I'm down to 180-195, though I still have the confidence of snail in a salt storm.  I've had chicks tell me that I'm a decent looking dude, now that I've lost all that weight and no longer have 2ft long hair, but they never seem to be the ones who want to date me, even though a few I would like to date. 

Now for me, I do graphic design, video editing, am a lyricist, and do audio work, along with whatever I can do to pay my bills.. I am self employed, so my paycheck isn't steady. I don't own a TV, nor do I care about religion or the majority of politics, cause they are both pretty fucked up.  I have damn near NOTHING in common with most people. 

Anyway, I can't carry a conversation to save my life, especially with chicks I find pretty and interesting. When chicks to come and talk to me, I am left with nothing to say. I don't get subtle hints or body language at all... How can you discern the common talk from "hey I want to get to know you" talk, or am I just forever alone?

Could you distill the essence of the text into 1-3 sentences?
<bot>: I'm a semi-boring person who has shit for confidence, but has been told by many that I'm a decent looking guy, looking to understand women's signals so I can stop being fucking single...
