I'm almost 30, female and still single. Will I ever get married? And if so to who and when?

No I do not think you will. I can't foretell the future, no one can honestly.

But if you are turning to psychics to find you a boyfreind and marriage, then there would be doubt

30 isn't as old and hopeless as you are making it sound. You still have your whole life ahead of you. Don't turn to this nonsense... live your life and things will fall into place.
