Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.

 

In order to have your marriage correct from the Islamic view, there must be a contract of marriage which is conducted in the Islamic way. This contract must include a bride and a groom in addition to two trustworthy Muslim witnesses and a guardian for the woman.

 

This guardian may be the imam of the Islamic center if your relatives are not Muslims. Moreover, there must be a dowry either included at the beginning of the contract or given up the consummation of marriage.

 

Having a wedding party by inviting people to a banquet is a different story. It is not compulsory. In case you did not make a contract in the way I have described, this is not a marriage and it does not put any responsibility. It is labeled adultery in Islam but responsibility lies only on this man who did not inform you.

 

It, moreover, seems that he is not a practicing Muslim and he deceived you by taking Islam as a way of getting married to you.

 

In this case. If you do not have a contract of marriage in an Islamic way, you must leave him immediately because he is not your husband. I suggest you ask him to do a contract of marriage in an Islamic way and show his commitment to Islam and encourage you to practice your religion, or you cut off all relations with him.

 

Allah Almighty knows best.
