They have no right to judge you. It's better to do things right than rushed. It's better to marry in your 40's with the right person and have your children grow up in a stable household; than to marry young, divorce, and have your children grow up in a broken home. And if you choose singleness for the rest of your life, so what? You are not hurting anyone. In fact, you can contribute to the community in a way that people who are tied up with their family cannot.
