Slept with my ex

Jess j
Ok so I slept with my ex yesterday. It was just supposed to be a friends with benefits kinda thing but he was all over me. Full off kisses and so gentle and loving with me. He made me a romantic meal. Now he won't leave me alone he won't stop texting me or anything. What does this mean? He was the one who broke up with me. But now he's all over me? I don't know what to think? Has he maybe realised how much he's missed me? I need help!!
