Annoyed - Venting

Fool me once shame on you...fool me twice shame on ME!!! You need to just forget about this fellow...I have no idea if you are just friends...or if you are wanting something more...but I don't think you need to bother. He doesn't seem like much of a friend...and he certainly isn't someone that I would want to spend time with on any other level!!!
The next time he calls...I would let the answering machine pick up...and then I would promptly forget about it!!!

This question can't really be answered. My answer, for example, if you were trying to sell him something would be very different than if you would be discussing a vacation rental or the possibility of dating.
This site is anonymous, so I don't see why you just don't provide some details.

With the lack of further details, I'd say he's just not "that into" whatever you were going to discuss.

Pencil him out.
Friend or not, whatever issue you were to discuss wasn't that important to him.
No more texts, no more e-mails, no more phone calls. If he does get around to contacting you....frankly, I'd be too busy to answer.
Seriously.
Guys can be insensitive jerks. This guy sounds like he is one. Don't waste your time trying to figure any of it out.
Write him off.

Sorry, that's just my blunt opinion.

my advice is to just walk away-its obvious hes just playing games with you-why feed into it??..hes being just openly rude an disrespectful...you didnt state the issue if it was buisness or personal-but actually it doesnt matter at this point-sounds like his ego is to big to carry around.if you see him in public again give a polite hello-only if he says it first-then keep moving on dont allow this jerk to play games an rent space in your head.life is to short-im sure theres more important things you could be dealing with.

he obviously no longer wants to expand on the discussion. Table it.

However, his behavior IN MY OPINION is rude but not returning phone calls and putting you off.

I'd have a talk with him regarding my expecting in a relationship - friends deserve respect too.

good luck!

Let it go and move on. Next time he says anything to you just smile and say "its all good". I wouldn't explain anything else.

Some people are yes people and will offer to do this and that in person and then once they leave, you never hear from them again.. I guess this guy is one of them.. I had a co-worker for whom when I left work would say, oh we should meet up after work.. I said ok and emailed her SEVERAL times to do so... and wouldn't hear back.. then I run into her on the street and she says again, we should get together , I say ok sounds good.. she says to me.. well you know where to reach me, I am always there.... never left.... to that , I think.. what.. I emailed SEVERAL times and you never responded ... in other words, the woman lives in her own reality.. which I don't think is reality.. it's just a comfy cozy place she likes to hang out.. :)

I would let this one go..

Who is this guy? Your boyfriend or love interest? What is this secretive issue you wanted to discuss with him? So mysterious!

Sometimes it's easier to receive a call than initiate one.

He may not be getting the emails.
