What are the chances he still has some feelings for me?

I think he for sure still has feelings for you, at least thats how it sounds. He looks at you and all those memories of your relationship come flooding back and he probably misses the good times you guys shared. At the same time he likes being able to do whatever the h*ll wants to with out consequences. It takes a while to get over any relationship, no matter how long it lasted, and my guess is just like you hes not completely over what you guys had. I'm sure he thought he was over you until you guys hung out and he saw you and realized how much things have changed. How you want to handle this is up to you, you could talk to him? See if he will open up to you and tell you what he's really feeling. Tell him you need to hang out with him one on one and just get everything off your chest and see what he says. OR you can move on, because honestly hun you deserve SOO MUCH BETTER. By telling you he "needs you" and all that he might just be making sure you'll hang on just a little bit longer, in case things get tough and he needs someone to fall back on. Which is a jerk thing to do. Find yourself a man who loves you for you, doesn't drink to be happy or do drugs, someone who makes you their world because they think your the greatest thing the ever walk into their life.
