Advice from men!

So the other day I was doing something with my ex boyfriend, all of a sudden he put his arm on me like he used to, next thing I know the sexual energy was threw the roof and we ended up sleeping together. We broke up two months ago and where in a long term relationship. He texted me later that day and said I hope you know I’m not using you for sex. Since then he’s texted a lot. Could he not be over me? He doesn’t wanna move on either but we broke up after a bad fight and he said he didn’t love me anymore... guys please help!
