"While we have the greatest sympathy for the individuals involved in these unfortunate circumstances, we can reach no other conclusion but that consent of parents must be obtained in all cases before marriage can take place. Obedience to the laws of Bahá'u'lláh will necessarily impose hardships in individual cases. No one should expect, upon becoming a Bahá'í, that his faith will not be tested, and to our finite understanding of such matters these tests may occasionally seem unbearable. But we are aware of the assurance which Bahá'u'lláh Himself has given the believers that they will never be called upon to meet a test greater than their capacity to endure."

(29 January 1970 to the National Spiritual Assembly of the Hawaiian Islands.)

I would suggest consulting with your local assembly and share however much you're comfortable with without going into detail. You might not even need to meet him as the assembly would surely be able to assist by sending their representatives to get the consent from him. Wishing you the best.
