22 years ago and he is searching for me, I'm a birthmom

UPDATE: So Saturday night we chatted on Facebook. My 2 sons (who he DOES consider brothers), and he was EXTREMELY EXCITED to find out he has a sister. It feels so liberating to be able to talk about this openly. However, one thing has struck me. He talks to his brothers and sister all the time, but rarely reaches out to me. I don't think its intentional or anything, if that makes sense. I am glad he is getting to know his brothers and sister (he definitely DOES consider them siblings, which is awesome) but suddenly I'm feeling kind of "left out" I knwo that its my hang up... but still... Does/has anyone felt like this? Thanks, Ronney
