Dating. What the?!

I admit.  Back in "my day" I was pretty good at snaggin' dates, being flirty and having a great time. But my goodness, the dating game has changed! I have been divorced a little over 4 years now and I've come to the conclusion that ... I am clueless about how this all works!

I'd like to know the "rules" of dating these days. Or at least your take on them.

I'm finding myself going back and forth about how I feel regarding dating more than one person at a time thing.  I tend to favor only dating one person at a time.  It is just too hard to keep all of the info, names and details straight! I feel if you believe someone is worth your time you should give them your full attention to give it a fair go. This way you know quicker if your wasting your time and truly gave yourself in full. If it doesn't work out then you know you gave it your all and you move on!  No?

And then how do you feel about the other person dating more than just you?  Technically they aren'y your boyfriend yet so they can do what they want...but what about someone feeling like you are enough to see through one way or another?  Am I too old fashioned?

Dating as an adult...and especially an adult with 2 children?  Insert crazy, confused look on my face!
