that there are a lot more people (than you thought) who are dating on the DL?
I'm way surprised there's this many married men & women on mingle and okcupid looking for partners, no shame.
My eyes are opened. Lol

also, the advice above; that's more for marriage, not dating.
Definitely don't take that approach... in the beginning.

Hello. I don't know how I ended up clicking the wrong link and ended up here, but I might have useful advice, I guess.
I can't speak for every woman, and I'm sure it's got a lot to do with which women you're pursuing (Choosing the right people is just as important)

The top reasons I don't respond to messages is because

1. No attraction (Sorry. >< Don't want to seem superficial but the top and maybe only reason a woman would be on a dating site and not respond to a message would be because she's not attracted to the person.)
2. Cannot think of anything to say based on an empty profile, little to no pictures, and lack of text in your greeting. OR the opposite, where I receive a paragraph of overly romantic text that is very vague and impersonal and appears as if it's been massed produced and sent out to everybody on mingle.
3. There's somebody else in the picture... and he's becoming important but we haven't made it to a real couple yet.

There are ways to build attraction. Like having a handful of pictures of you out doing things, with friends, or creative selfies.
Fill out your profile. (!!) add some depth or talk about something you're passionate about. You don't have to list all of your 'goals and achievements' either. If you can keep it concise and intriguing then a girl, who you messaged, who has already been drawn in by your pictures, will be intrigued to know more about you and have something she can use to respond.
