Guys, How long does it take for a guy to come back?

he’s a player... well likes to think he is anyways lol
SO he asked me to hang out and come over and I wasn’t able to as I was busy. However I saw him 2 weeks ago. He’s been messaging me since as well.
2 days later he says he thinks we should stop our friends with benefits which is fine however how long does it take for a guy to come back? Why does this guy run hot and cold? Do guys regret ending a situationship in the heat of the moment? Please if you can answer these questions ☺️
