There's a difference in my honest opinion, about not wanting to be in a relationship right now, and not wanting to be in one ever. I don't think wanting to take time for yourself and your healing would be in any way bad. I don't think taking a decade of personal love and self reflection is bad, even. Living without finding "the one" is completely fine but I wouldn't commit yourself to a lifetime of it, rather take a sort of "if it happens it happens, I'll be the same regardless" approach. We make enough lifelong decisions at the early adult years, what job/degree, college, work, marriage, kids I don't think adding to that will help.

Basically I wouldn't commit yourself to -never- being in love with someone else, because if you do you can miss something or bury feelings and neither is, in general, healthy.
