How to get over him

I recently had a break up, it was pretty rough because I didn’t want to break up with him but things weren’t the same. It was a clean break up but I miss him! I find myself flirting with others to distract myself. I’ve debated on sleeping with someone but I don’t know if that’s a good idea because I’ve only ever had sex one other time and I’ve never been the type to just sleep with someone. I thought sleeping with someone else might help me get over him, I don’t know.
