my head is spinning

I try to stay positive with my open adoption. Lately it's just hard... I wrote the a-mom an e-mail hashing out my graduation plans in June, they're coming along with a ridiculous amount of my family. I told her in the e-mail that I had really been missing my b-son lately and to please tell him i love him and give him kiss. I also asked if we could get together the day before graduation because they would be in town. She replied and did not even acknowledge what i had said about struggling lately, or letting him know that I had sent my love. It was completely dismissed. I'm not expecting a pity party but is ACKNOWLEDGMENT too much to ask for? It really took a lot for me to express that to her. I read these other posts where b-moms and a-moms discuss so many aspects of their adoption and I'm envious because i don't have that. As far as getting together the day before she said, " i'll call you when we get into town." That's it. No plans, no excitement at the idea, no tentitve time i can expect them...nothing. So i guess I'm suppossed to sit around the phone waiting for them. All of the contact for the last eight years has been put on me. Never have they tried to plan a visit or call me just to say hello. Every visit but one i have had to travel to them. Our relationship is so one sided and it's really starting to discourage me. And now, i know they're coming soon and it's bringing up all these emotions.
