I think the concept of letting go of the need to feel rejected is part of letting go of all of it. That's a victim mentality and letting go of that is important to all of us. We are not victims, because that idea keeps us stuck. What happened, happened.
As for you, do you feel attracted to people that are "hard", "undemonstrative" etc because of your family history? Maybe. Probably not, but it's something only you can discern.
In some ways we do pick people that seem "normal" to us. Normal to us is what we are accustomed to. We grow up with and see "normal" modeled for us. Part of us growing up is figuring out if "normal" is what we want. It's a strong pull though not always what we want nor need
