Good for you for not bowing to pressure to connect with someone whom you did not feel ready to. These expectant parents need adoptive parents who are willing, ready and able to parent their child and that's not you. And that's OK.
We declined several opportunities to connect with expectant parents making an adoption plan, for a variety of reasons. One honestly because we didn't 'click' with her, and couldn't forsee having her crazy life a part of ours. Another because the substance use during pregnancy was very high and we did not feel comfortable with the ramifications.
Honestly, who cares what the agency thinks? This is your life. Wait for the situation that feels absolutely right, where everything just 'clicks'. That's your connection.
BTW I hate the term 'match'. You're not identical, nor are you a set. That's why I use the term 'connection' - because that's what it is. You're connected by mutual agreement, for a single purpose - to care for a child. That's just me though.
JMHO
