Single Mom's Dating

Being newly single for the first time in like almost 6 years I've found myself at a point to where I don't have answers or even suggestions for myself. i try to think what my answers have been or would be to a friend and coming up blank...

Whats the rules for dating as a single mom.

Do the kids meet the guy? If so do they meet him as a friend as in he's over to hang out and watch movies or wait until there's something serious?

How do you handle over night stays when you have kids? Or are you even suppose to have them?

I know for each person its very different as to what their comfortable with and what their not but its confusing to say the least. Can you show affection in front of your children. I always thought it was healthy for children to see 2 adults share love and tid bits of love...I'm not talking about straddling a guy and going to town but what about little kisses...and hugs...acceptable or not?

There's alot of uncharted waters I'm walking in here lately and not too sure how to go about it all but just testing things out to see how they go. I was single when I met my X husband and only had Taylor but obviously the ways I went about things there were not the right way...lol

I'm interested to hear what the single moms out there have to say about this...how do you approach dating or sex for that matter....I'm just going to put that out there...cause I'm curious. So, whether your single or not I'm interested in your opions.
