[Sniffles]

Been there, done that. I know just how you feel and my prayers are with you. I was able to contact my b-grandparents and they in turn talked to my b-mom. Well she was very upset too, but she has never contacted me.
I do keep contact with my grandparents. We talked on the phone for an hour the first time and traded e-mails back and forth. The last e-mail was before Mother's day and I didn't hear anything from them for awhile. I was freaking out. My computer was broke at that time also so I had no way to tell if they e-mailed me. All kinds of thoughts just ran through my head.
I finally called them a few months later and they were happy to hear from me. They told me that no matter what they will always keep me in their lives. They were very busy during that time and they were traveling most of the time. The morning I called her the second time she had e-mailed me that morning to basically let me know that they had not forgotten about me.
Don't worry things will turn out alright, she probably got caught up doing things. If she has 3 little kids then her time is definatly taken up. I have 2 myself and they are a handful.
