Marriage

Virgin girl does require in her marriage the permission of her father or her paternal grand father. If father and the paternal grand father refuse proposal of marriage with out valid Islamic reason when the proposal is from a Kof’ (Compatible believer) and the girl needs to marry to save herself from sin, then the condition of the father’s permission or paternal grand father’s permission will not remain. That is when the refusal of the father or his father is not based on a valid Islamic rules.

You should make sure that your future with her as a wife and mother of your children is peaceful and harmonious with out differences. She must know the main facts of Shia Islam based on the following if the Ahlul Bayt (AS) being the real successors of the Prophet (SAWA). Give her few books to read e.g Then I was guided by Dr Tijani, The Right Path by Sharafuddin, and websites like aqaed.com.

She need to understand the Shia faith from Shia sources and not from the opponents.

 Don't risk your future and your kids future in a marriage before being sure that it is based on full understanding and accepting the facts of Ahlul Bayt (AS).

I did not find any evidence supporting the claim that Imam Musa Al-Kadhim's daughter was married to a prince of Azerbaijan, nor any evidence of any son of Imam Ali Al-Ridha (AS) buried in Azerbaijan.

Those who claim that should give their evidence if they have any.

'All our most knowledgeable Ulama (Maraaje' of Taqleed) say that marriage between Sayyeda believer and Nin Sayyed believer is allowed as we don't have in the authentic narrations from the Prophet (SAWA) and his Ahlul Bayt (AS) any evidence against it. They have long list if authentic narrations e.g. in Al-Kaafi , an authentic Hadeeths from Al-Hadhrami from imam Ja'far Al-Sadiq (AS) : The Prophet (SAWA) arranged the marriage between his first cousin sister Dhubaa'ah Bint Al-Zubair ibn Abdul Muttalib and Al-Miqdad ibn al-Aswad. This is a clear evidence that Miqdad ibn al-Aswad who was a Mo'min but non Sayyed was been helped by the Prophet himself (SAWA) to marry a Sayyeda Mo'mina who was the first cousin sister of the Prophet (SAWA).

We also have a Hadeeth in Al-Tahtheeb (number 1581) stating the same marriage between the Prophet;s real cousin sister and Miqdad ibn al-Aswad arranged by the Prophetvhimself (SAWA).

Direct communication with potential spouse must remain within the frame of Shariah as both of you are still Non Mahram to each other. Flirting or flirtation with a potential spouse remains Haraam till both of you enter in an Islamic contract Aqd which allows that. Chatting should never contain any emotional content before having a valid Aqd between you. If both if you want to meet, it should be in the presence of another person to avoid the Khalwah (private meeting) which is not permissible with out a valid Aqd.

Any man who commits the major sin of fornication with a married woman will be forbidden from marrying her for all his life. He can marry with another woman if she agrees but not that woman with whom he committed the crime of fornication while she was married even if she is now divorced or widow.

As a virgin Muslim girl, you need your father's or your paternal grand father's approval for your marriage. If your father's refusal is based on un Islamic reasons, then you might try convincing him through your relatives of family friends who can talk to him. You should always keep the respect for your parents and never utter  a word which can harm their feelings. 
In case your father insists on rejecting for un Islamic reasons, you can refer to you Marje' of Taqleed and seek his advice or verdict after explaining your situation.

Wassalam.
