Ex boyfriend

Mutual breakup with my boyfriend less than 4 months ago. We've hooked up like 3 times since, with stay over and a date the next day. Like it's beyond hot!! I can't even describe...like one look at him and I don't even know my own name 🙈 even though we agreed to just be friends which was working but then one night I was out and we were talking and then he kissed me and all my good intentions went to hell. We talk/text nearly every day. He's not seeing anyone, I'm not seeing anyone. I don't know what to do or say. Please help!!
