Hi.
There's nothing wrong with deciding not to date. In fact, it's a good idea to wait until you are comfortable. If you want to wait until you feel old enough for dating--whatever that age is for you--then that is absolutely your choice. More power to you for knowing not to get involved in something that doesn't feel right.
However, dating is definitely not all about heartbreak. Two people can date and be very responsible, caring, considerate and even loving toward one another--and later decide to stop dating because something isn't right. If it's a mutual decision, there may not be any heartbreak involved, just an understanding about what works and what doesn't work with this particular relationship.
Think about why you feel the way you do about dating. Is it from seeing your friends or peers date people and then go through bad breakups? Do they lack the judgment to pick boyfriends or girlfriends with maturity? Do they understand why their relationships end when they do? Maybe if you think some of this through, you can better explain your position when telling people about the choices you have made for yourself.
