It all depends on you. If you think you can hold a friendship with this kind of person, go for it. But also keep in mind that you know the kind of person he is.

If you still have feelings, friendship now will be really hard. I suggest you wait until you are over him completely.

"Friend" is a very flexible word - it can mean just about anything from "a person I know a little bit and can get along with" to "the person I know best in the world". In this case, it sounds to me that he's using the "someone to keep around in case I wanna have fun" definition of the word "friend".

If you're OK with that, enjoy it; but if not, you probably want to let him go.

He's about 5 years away MINIMUM from not using comically absurd excuses for a break-up.

I'm afraid that the truth is he did not "love" you.
He was in "Lust" with you. But the good news is that means you are rather attractive. I am sure.

Next time, you decide who you want to sleep with and
If it's a player... ok. If it's not, OK. There will be OTHERS.

Avoid him. It's OVER.
