So me and Michael have been best friends since junior year. I had a crush on him freshmen year but he was in a relationship so I put my feelings aside because it wouldn't have been good to act on them. I dated a bit but never really could focus on anyone the way I focused on Michael. When Michael broke up with his long time girlfriend, I hoped things between us would spark but he told me his feelings for me were purely platonic. A week or so after he said that, we were hanging out at my house like always, watching cartoons and eating breakfast (we're both over 18 by the way), and he hugged me. For a very long time. And that hug turned into a friendly peck on the lips. Which erupted in a frantic make out session and then sex. I didn't push. I was fine being in a no strings relationship with him at the moment but after a while, it seemed like we were heading in the direction of a relationship. And then his ex realized we were getting closer than she liked and she told him she didn't want to talk to him anymore. She has a history of depression so of course he stopped things with me and ran to her to make sure she was happy. He loves her, I know he does. But for a time, sex aside, it really felt like he was developing feelings for me. Last Thursday, he came over to my new place for a house warming party I was throwing. He said he missed seeing me and that he really hoped I was happy. I'd overdosed on Vicodin a few days earlier and somehow word got around to him. He told me how upset he would've been if I'd died. He said I was his best friend and while he could handle me being mad and not talking to him, it was much better that way than if I was dead. At first I believed he truly meant that but now I kind of feel like he just doesn't want to deal with the guilt. We talked a bit more after everyone left and I opened the door for him to leave and he closed it and led me up to my room. I followed without a word. We had sex and just laid in my bed for a while. Then he cursed and said he didn't come here for that and that he was sorry and he shouldn't come over for a while until I get over my feelings for him. Am I just being manipulated?

In reading this he may not want to ruin the "friendship". Something's are better left where they are. Yes you had sex... Yes you started getting feelings. Sounds like he separated himself to keep from going deeper and both of you getting hurt and losing the friendship. Let it alone and if he comes back and initiate sex tell him "No". You want this to be a friendship only.
