watchful

I am very watchful of who has the privlege to meet my daughter. About 95% of the people are female. On the off chance i run into a male friend or acquaintance, i have never bothered to introduce Emma. But now, she is 4 and 1/2 and asking questions about everything and everyone.
Funny story, we were in church on a Sunday morning and she asked in her not so whisper voice why the old guy next to us had a tank. I quietly explained it helped him breathe and he was not necessarily old, just older than her. But seriously who am I kidding? She is 4 and 1/2 and he had to be almost 75...to her he is OLD! She thinks I am old...even though i tell her I am still just a kid. Lucky for me, and unlucky for me Emma picks up on everything.
Back to introductions. When exactly is it okay to have her know who i run into at the grocery store?
And, if i am thinking about quite possibly finding someone of the opposite sex attractive, (ha like that is going to happen in the next 5 years!) what is protocol for the meet? How would I even think about going about it? Lets face it..i haven't had a date in over 6 years! What in the world do I even know about dating? What is the protocol for a single mom to date? I think that is the best question yet!
Okay, so i know the basics, if i feel good, i look good. Like Stephanie says, a glass of wine to take off the edge...but still. The nerves are already rising just thinking about this!
But there is a guy and i do think he is cute...and once i get beyond the nerves...its more than one sorry Steph...i think he is a nice guy. But i am so jaded. No, not jaded..just hurt and mistrustful. Saddened by the fact that I did not find happily ever after with the man who made the promise. When exactly will i get past those feelings? Then the extra bonus the total mistrust? The lack of faith in the opposite sex? The feeling that no matter what he says or what he does, he has an alterior motive.
He thinks he is my rebound..i say rebound to what a crappy 2 years? Hello! Yes you are!! Oh, here comes another one...what exactly is a rebound relationship? Why is it called a rebound? Oh the questions and thankfully oh the therapy. :)
When do i draw the line in the sand and say should i cross this?
