Getting out of a date that I don't want to go on?

Be honest but kind. Tell her you agreed to go out for the wrong reasons and that she deserves someone more truly interested in cultivating a relationship. Ask her to accept your apology and beg off from the date.

If I’m her, and I have a crush on you, the kindest thing you could do for me is to be honest and not leading me on, though I wouldn’t need to hear the whole truths.

Don’t worry! I’m sure there will be many more to come…

Go on the date because if you not try it out the date will get postponed.

Do things that you usually do solo to make her understand the reality.

Do tell her gentle that you don’t want a relationship.

Anyway good luck.

the easiest way to avoid this getting weird at work is to just suck it up… go on the date, and then let just tell her you had a nice time, but you didn’t feel chemistry and think it shouldn’t go further.

That way you don’t become “that guy” and you give her a little validation. Also you avoid looking like an ass after making the date and canceling, which will help avoid any uncomfortable situations at work.

Good luck.

Breaking the date could make thinks awkward at work. Treat it as going out with a friend, and tell her you’re not interested in dating someone that you work with. That alone is enough reason to not date someone, without bring up the other two reasons. Keep it to a short evening, take her home, don’t go in afterwards.

Personally, I am for the be honest option and not going on the date. I would use the “I didn’t think it through properly but on reflection, I just don’t think it is a good idea to mix business with pleasure and I don’t want to lead you on by going on this date. To ease the blow, perhaps you could say you could go out as friends for a coffee or something but you don’t want it to be a “date”.

Tell her the truth and be quick about it. Chances are she is planning on having her hair styled and her fingernails done, just for you and this date.

Do not let her “hang” any longer.

Be nice, be tactful and apologize to her. She may have been waiting for this time with you, forever.

This is all news to you, so off the top you haven’t been checking her out or considering the possibilities. This might be the perfect match only because she doesn’t meet your strict list of perfection.
She may have qualities you never considered important, and maybe you aren’t her perfect guy. But she wants to take a run at you, and you really should go for it to find out. I know guys who avoided kids and wound up loving the whole situation afterward. Date every chance you get, because the pool gets pretty small real fast and you will regret being so picky. If anything, more interested girls will know how easy you take invites and go for it, knowing they won’t get shot down.
Do it, have fun, then consider the situation once you really know beyond a first glance.

Tell her that you have thought about it and you do not think it is a good idea to date co-workers.

@noelleptc I keep asking myself the same thing.

To Everyone else: Thanks for the advice, I will just go through with the date and then politely say I am not interested.
