So........a few months ago I met this guy who I thought was sooo freaking cool. A perfect mix of what I am looking for in a guy (minus his prison record, the fact that he is a compulsive liar, and that he doesn't really like the news or politics or reading).
Anyway.....he came on strong, then turned off just as strong. Everyone who cares for me doesn't like him because he is kind a jerk towards me.
Ok, here is the deal---most guys would say "hey, chick, it isn't working out between us" or "I just don't like you in that way", etc. What he does (I will name him Tall), is that he just does a put down. I say "Hey, babe, long time no hear. How are you?". Tall says 'Leave me the f*** alone!" or something like that, out of the blue. He will never answer why he is suddenly upset at me, and he will just reply with some weird put-down.
Now, rationally, Tall is a guy that I should not even talk to. If he cannot talk to me (and he is almost 10 years older than me) like an adult, then, what is the point in talking? He does do childish put-downs, but they are so sudden and out of the blue, that yeah, I have cried at least like 4 or 5 times over this guy....and we were maybe a couple only for a couple of weeks. Sigh. Yeah, he came on very, very, very strong and I foolishly got all goofy in love.
So, I thought we weren't talking anymore (after he said he didn't want anything to do with me), and then, after a day of being very lonely, he went out with me, paid for some things, and was just generally very nice. I even joked with him that it wasn't so bad hanging out with me as a friend. He said it wasn't.
Now, I am trying to not get all goofy about him. I realize he lies a lot, and I don't know why he spent time with me, or why he is suddenly not cursing me out and that considering everything he has said, the odds of him suddenly really caring about me are very small. But, a small part of me does kind of hope that he becomes nice and does have feelings for me.
I know, I know, that is super silly. Sigh.
Have you ever liked a guy you know you probably shouldn't, but you just had this weird attraction to?
Also, what would make him change? Did he just feel sorry for me?

Can't say I blame you. But he does not sound like good news.
Read that back over yourself as if your best girlfriend had written it. Would you give your blessing to a guy that would treat her that way? He sounds a little manic depressive to me, up one minute and down the next, radically. If you want stability, this is not it. You deserve to be treated like a queen, never cursed at!! 
this might not be your situation at alll, but it was mine for sure. When I was in high school and in my first year of college I weighed 345 pounds, and oh my God did I date the biggest jerks out there. And I dated many. But because I wasn't a size four I think I didn't think I could do better. I didn't have the confidence. I allowed those guys to treat me like that and I'm not entirely sure why. But no that I've lost my weight and gotten confidence, I look back on it and I'm like what the heck was I thinking!? I was beautiful, smart, funny, and I did NOT have to settle for that crap. Loser guys who would call me names, then ask me to come over to watch movies the next day. Wow, I'm embarassed to say that I ALWAYS went for it. And now, I'm quite a bit thinner and I'm attracting not only good looking guys, but nice sucessful men who treat me right. Who want to treat me right. But I know now that I could have had that back when I was at my highest weight... If I'd just believed that's what I deserved instead of losers with criminal records who lie. Now, they try to talk to me on facebook- the losers- and I get the skeevies (idk if that's the word but I get grossed out). Its like I want to deny that I was ever stupid enough to go for those loser guys. Blah! Haha but such is life I guess. You live and you learn, but take it from me that you don't need to settle for losers. Don't be like me and settle for whatever reason, be it lack of self confidence or just.. Boredom and love of the attention (I loved the attention too). Idk maybe your situation is nothing like mine but you sound like I was when I dated those idiots..! I told myself I was into the bad boy thing, but noo. There's a difference between a bad boy and a downright loser. Your guy sounds like quiiite the loser. :/
