Are the pics from her profile the ONLY thing you have? If so, don't base it purely on that. At least meet her in person first. If you still don't want to date her, you never have to see her again after that.
So I am in a pickle. I met this really cool girl on a dating website, we have a lot in common, got her number, been texting, but she's not exactly the most attractive. She's just average. Part of me wants to take her out cause we've been hitting it off, but I also don't want to waste time and money on someone who, based on her pics, isn't the most attractive girl I've been with.
Just remember, it could turn out BETTER than you think. I have sort of the same situation, but I can't really tell much because she only has one picture. I meet her for the first time tomorrow. I had a date once with a girl that looked fairly attractive on OKC, and then in person she was even MORE attractive. So things turned out for the better there.
