I think you are being unfair to yourself when you say that you don't want to be in a relationship until he is in HS.

I know why you would say that. Why expose your child to many different guys looking for the right one? Thats unhealthy.
I just think you need to be smart about it.
Obviously, I have no idea how old you kid is but I am sure that your intentions are good.

You need to live. I mean face, women have needs too., right?
Just be samrt about it

As for the email, Its just email, are you going to meet up with him in the future?
