So, I’m not a guy, but I am a gal in my late 20’s who also has never had any interest in dating a man with kids, so maybe I can still shed some light on this:

For me, there’s a number of factors. First off, well, I just don’t want kids, let alone somebody else’s. So that’s a problem right off the bat. But for the sake of the discussion we’ll ignore that. Another issue is that relationships already involve taking on a lot of another person’s baggage, which is normal and okay, but adding a kid from a prior relationship into the mix is just a whole other level of baggage; now I have to develop a relationship with this kid, I’ll be expected to have some responsibility for it, your ex is most likely still somewhere in the picture, and it’s just a lot to expect somebody newly entering your life to want to put up with. Some people are up for it, and that’s totally great, but it shouldn’t be a mystery why many aren’t. There’s also the fact that, quite frankly, single parents and/or divorcees are too often bitter and jaded about relationships... and that really sucks for somebody with a lot of life in them still, who’s excited to build a life with a partner. To have to wade through your insecurities and your mistrust and your cynicality. Of course this is not true of everybody, but it would be a lie to say that it’s not true of many.

But alas, now here’s the part that a lot of people aren’t gonna like... the fact I’ve been spending my adult life making careful decisions and meticulously crafting the life that I want for myself. I have made sacrifices, I’ve shown restraint, I’ve worked my ass off and I’ve got to say I’m doing pretty damn well. A divorced single parent comes along... and I see somebody who made poor decisions, who didn’t plan ahead, or who does not have the restraint to wait and assess their options before diving headfirst into huge commitments. And like I said, with all of this comes various types of baggage like your ex, your child support payments, and things of that nature. And honestly, while it’s your life and it’s totally up to you how you live it and I’m not saying that anybody who isn’t like me is wrong — I am saying that I would much prefer the company of somebody who has valued patience and planning in the way that I have.
