Dilemma

I'm in a sticky situation and I need some feedback.

A close friend of mine (A) recently went out with a guy that a common friend of ours (B) set her up with. She called me after the first date, sounding very happy about her evening and with great hopes at least towards a second date. 

Which never happened, because he immediately felt like they weren't good for each other and did not want to lead her on any longer.When she called me the next day to complain about how guys should give second chances, I sympathized and called the guy all kind of names (just kidding).

Anyways, yesterday I bumped into B and we started talking about life, girls, boys.... Naturally the conversation came along and we found ourselves discussing A and the guy. I was happy I talked to her about it because she gave me legit reasons why he said no that she couldn't necessarily tell to A. The more she told me about him, the more he sounded like a guy I could go out with.

Bottom line is I am going out with him, first date has yet to happen but probably in the week to come or so...

The question is do I tell A beforehand or do I wait to see if there is even a point in telling her? I do not wish for her to feel under evaluated as in like he's just dating girls in passing till he finds the one, one being no more or less special than the other. Then there is this neurotic concern on my part, that if it does go somewhere, I can't have her feel like he choose me over her. 

To tell or not to tell?

Second date killers

You go on a first date, you have a good time.
You come home happy, you agree to meet again.

Second date comes, you're already more comfortable. After all he is no longer a stranger. When that second sate drags along, you are pleasantly surprise. He talks, he flirts, then he drops you off. He tells you how great it was to see you again and that you will be hearing from him. You come home happy, already thinking about a third date

The next day, you have yet to hear back from your date. However, as the day goes by, you start wondering if perhaps you should contact the person who set you up. You hate to be the one making that call, but you tell yourself it could be worse (had you had to call up the guy himself...).

Next thing you know, there will be no third date. You're an amazing girl but you're just not for him.You were not mistaken, you just don't understand.  He really seemed to enjoy your company. He enjoyed stretching out that second date... So what killed it?

Sometimes you'll hear that you're just too good for him, or that it isn't the right time for him..

So why the need to stretch out that second date? Why make it so intense, full of hope and future instead of taking it slow? Why risk portraying the wrong image leaving someone bewildered behind?

He doesn't know and you don't know. One thing WE girls do know is that we'd like boys to be more cautious while dealing/playing with a girl's heart. This request is by nature complicated, we know...but don't we all wish...

If you are that girl to whom second dates mean a lot, perhaps it is time for you to move up your reference bar to the third date.

Because to my roommates, to my friends and to whom ever cares to share, I can no longer be making excuses for all these guys, whatever they might be thinking...
