<human>: Give me a shortened version of the text

I've had 2 real relationships in my life... the first started in high school and lasted 16 years.  I've got 2 great sons ages 7 and 10 from the first, and they were heartbroken when the second relationship ended because *her* daughter and *my* sons got on like siblings.  So naturally, I'm a little gunshy.  

I'm hesitant to get involved again because I don't want them to get hurt by the way my heart leads the charge.  I do online dating exclusively, I'm just not the kind of guy who approaches women at the grocery store (in front of her kids), or at the playground (in front of her kids), or through work because I work from home and dating a co-worker didn't work out for me the once.

So I've tried twice with a 'friends first' approach and both times, she was sticking her tongue down my throat before the end of date #2 when I thought I had made it clear that I wanted a friendship to turn into a great romance.

But is that even possible??!  I think it is because both of my real relationships were with girls I'd known for months or years prior but then again both ended poorly.

I just feel very frustrated, because I'd only started dating a year ago and after having gone on 30+ dates, I feel I am no closer to finding the kind of woman I want to share my life with.

None, not a single one of them were even in the ballpark of what I want and I honestly don't think my expectations are all that crazy.

The only thing I can come up with is that the kind of girls I want (intelligent, active, affectionate, has kids, and is not crazy) are usually already happily married.  The ones who aren't don't do online dating for some reason.

I feel like I am firmly entrenched in my rut and I have no idea what I'm doing wrong.
<bot>: Is it possible for guys and girls to be friends first, hang out, and strike up a lasting and meaningful relationship?
