Most Helpful Guy
While I do not know you or him, I think I know what he means. He says he wants some time to "chill" and "do him". Very bad phrasing, but guys are often like that. We spend lots of time thinking about how we feel about something and when we are about to explain all that in depth, our brain freezes and we put all of that into two sentences, especially when we are talking to girls. He says that he loves/cares about you and more importantly that he wants you in his life, but he just wants to chill. I assume that he is tired of all emotional obstacles and that he is unsure if he would be happier with you or with someone else, or by himself. So he basically wants some time to see how he actually feels. You just have to decide if you want to wait for him to figure that out.

He wants to be free to have fun and only worry about himself. Having you around means you are in the way. He wants to be free to sleep with other women. He may or may not be back around when he gets it out of his system. Most likely not, though. My advice is that you move on and don't look back. Do YOU.
