This dude is playing games. He knows you hace feelings for him and is using that to manipulate you. Somebody else is likely involved or at least, he's looking and using you as a place holder til he fills that void. Don't play his game, don't be used. Find somebody who'll respect you and put you as a priority and not as an option or rebound. Plus, usually when people start hitting you with that "you text me/contact me too much" that's usually code for they no longer love you anymore because it surely wasn't a problem when y'all first got together and it won't be a problem with any new girl he's with or is talking to1

Hahahaha, first, my best friend went through this same thing with her boyfriend a couple years ago, and he was completely full of SHIT. He told her she couldn't date anyone but they weren't together. He said she was bothering him too much but he needed space. But he always called her everyday and wanted her to come over. That dude came crawling back after 6 weeks.
I mean, literally, this is the same story she had. Almost exactly the same story. Give him space. Don't talk to him. If he texts you, tell him you need space, too, and that you want to be with him, because you do. And tell him you aren't going to have sex with him. You guys are friends. The end. Be stern.1
