A guy asked you out then dupmped you later that day and lied about it but you went out with him again ad he dumped you after 3 days should you ask him out again?

l'd say... NO.

First of all, he asked you out, and then decided that maybe it wasn't what he wanted to do in one day. Then, he lied about it. Lying is not a good sign.

And, to top it all off, you went out again and he proceeded to dump you in 3 days. Yeah. Dating him again would probably result in the exact same thing.
