Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Both of you did very well by preserving your chastity and not committing forbidden matters like being alone with one another, or resorting to forbidden looking. This is what people in love should do. Moreover, you behaved appropriately by trying to get married, as this is what should be done when in love. You also behaved appropriately by trying to get married, as this is the best cure for this love. Ibn Majah reported that Ibn Abbas may Allah be pleased with him, narrated that the Prophet (Sallallahu Alaihi wa Sallam) said: "The best solution for those who are in love is to get married."
Our advice is that this gentleman take the initiative to convince his parents that he should marry you, and he has to do his best in doing so. He has to seek help of the people who could convince his parents. Supplicate as much as possible that Allah may decree for you what is good for both of you either in the short or long term. Seek His help and ask Him to render what is difficult easy for you. For instance, you may supplicate with what Ibn Hibban reported in his Sahih that Anas narrated that the Prophet (Sallallahu Alaihi wa Sallam) said:
"O Allah, nothing can be easy except that which You make easy, for You make any hard matter easy if You wish." Ultimately, if his parents agree about their son getting married to you, Al-Hamdu Lillah (Praise be to Allah); otherwise he has to put the obedience of his parents over getting married to you, because being dutiful and obedient to one's parents is an obligation while getting married to you is not. So what is an obligation takes priority over what is not. We advise you to continue making Dua to Allah to grant you a pious husband, as perhaps the good is in getting married with another man, and remember the saying of Allah: "...and it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know." (Al-Baqarah 2:216)
Finally, we draw your attention to the fact that it is not permissible for a woman to travel without a Mahram or to mix with alien men in that country, the people of which have no religion which prevents them from committing adultery and being involved in despicable and contemptible matters.
Allah knows best.
