I've wanted to post this question for a while but I've been hesitant to "put myself out there" so to speak.
Background Info: My sons amother contacted me about 4 weeks ago via email. I was elated because up to that point I had only been able to write her via the agency(closed adoption until last year when my son turned 18). We have exchanged emails a couple of times as well as letters and pictures. In all her writings to me she sounds very loving and kind. She also sounds genuinely interested in my family and how we are doing. My son has been cautious about writing to me (he's 19 and in college), so the only information I have about him comes from his mom (which I am VERY grateful for).
Here is my problem: I'm an emotional wreck waiting between emails. I'm scared to death that I will say something wrong

and she'll end contact.
It has been 11 days since my last email to her and no response yet (she told me if I had any questions let her know and she would answer them, so I asked a couple of questions in my last email).
Anybody else deal with these feelings? What worked for you? I know this is completely "my stuff" and that she is most likely just busy with everyday life stuff.
